Poor Gary Kildall never really gets the recognition that he really should be entitled to after the enormous influence he had on the early personal computer market. He very easily could have found himself supplying IBM's OS instead of Gates and then Microsoft might not even exist today. I always enjoy watching him interact with the various guests on the Computer Chronicles, he really comes across as a friendly, knowledgeable expert, without Gates' harsh mercurial edge.
Yawn...
Worse than unappreciated, before his early death he saw the decline of his company, which he had originally called "Intergalactic Digital Research". He wasn't much interested in he business side, initially leaving much of that to his wife. Also, he was part of California culture when much of the computer business and culture; namely IBM, DEC and boffins at MIT, were still centered in the corporate northeast. It would take a few more years for Silicon Valley to eclipse them all. Unfortunately his misfortune became a learning lesson for the future California dreamers. Then, his reputation wasn't based on his many achievements, in fact a myth circulated that he was pursuing his hobby of solo flying, keeping reps from IBM waiting, and that's what scuttled the deal with them. This was untrue, but it was at least based on his disdain for the business side of software. That end was more cruel, than how he may presently be less appreciated. When the "gone flying" myth recedes from folklore, I think he wrll be remembered properly.
He had multiple opportunities to break through and unfortunately he blew them all.
Correction: There is a caption error under Paul Allen, this should read (1953-2018). Hello Cave Dwellers! As many of you find yourself in isolation or working from home I thought we'd try a Premiere to watch a release together! Let's see how it goes, Neil - RMC

@@MrJ0mmy If you can't catch the premiere it remains listed on the channel just as per a normal release. I'll keep this in mind though, if it goes well I can mix up future release times so that I can get to chat to more of you
Honestly this is a great idea, really appreciate the thought. Love the content too, which definitely helps!
I wonder why KZhead doesn’t allow you to make updates to an upload. Other sites, like Vimeo, do.

Thank you for sharing this, I didn't even know there was a PC-DOS 7 / 2000. I was the QA Lead on the Microsoft MS-DOS line from MS-DOS 3.3 to MS-DOS 5.0 My team of only two testers avoided the PC-DOS 4.0 major bugs and won control back control of the design because of it. MS-DOS 5.0 was developed using a small fraction of the size team than the PC-DOS 4.0 team. The team moved on and created Windows 95 later.
James L. Yep, 4.01 was a good polishing of a... still a bit hairy, but given the source... I remember getting all giddy when my new computer came with a boxed MS-DOS 5 - that manual ended well thumbed-up!
Was that the Multitasking DOS 4.0?
Thanks for the history lesson. I got into computers in the early 90s, and this brought back so many memories. I grew tired of MS, so I bought PC-DOS. (I believe 7.0.) A feature I loved, was the memory management. Prior to PC-DOS 7.0, one could squeeze a bit more free memory out of their computer if they ordered their device drivers in CONFIG.SYS and AUTOEXEC.BAT in a specific loading sequence. This took a bit of trial and error. PC-DOS had a feature that would re-sequence device drivers, automatically reboot, check the available memory, re-sequence, and reboot again, eventually finding the perfect device driver loading sequence. Fascinating!
Are you referring to RAMBoost when you said it'd restart several times? I believe that was IBM's response to MemMaker and Quarterdeck's Optimize.
My IBM 5150 is currently running XENIX! A previous owner had upgraded the machine with a beefier power supply and 10MB Seagate hard drive, so it was quite straightforward to install XENIX using floppy disk images and a HxC 2001 floppy drive emulator.
Too bad XENIX (and isn't it pronounced XEENIX (ee like in "see")?) is still proprietary though discontinued, while CP/M was open sourced in 2001 I guess. Would love to run it in a IBM 5150 in an emulator. I already did this with CP/M-86.
@@TheAnkMan XENIX isn't open source, but the original Unix source code that it's based on is. Bell Labs distributed it in source form, and during the time the rights to the code were owned by Caldera they put it under a much more permissive license.
@@chriswareham Yes, some UNIXs are open source. I also use FreeBSD and OpenBSD. But I am interested in running obscure operating systems. Besides MP/M as mentioned, I ran OS-9 (not the Apple OS) in an emulation of the TRS CoCo kzhead.info/sun/qdCmkqeFopqsZ2g/bejne.html from 1979 to show its multitasking capabilities. And CP/M on other computers, like the Osborne I or Kaypro, doing some word processing and trying out, how the first Speadsheet programs felt like. Not even Ebay seems to have a package with diskettes for Xenix available.
@@TheAnkMan i was a manager at a Tandy Computer Service Center in the early 1980's ..When OS-9 came out the company saw it has a slight improvement on their cartridge based game machine TRS Color Computer..then we started seeing customers setting it up run with multiple dumb terminals and the company went crazy ..there was a fear that some how the TRS Coco would take some business away from the Model II (soon to be the Model 16) running TRS-Xenix ..or even worse might replace the Model III in in school environments (up to 16 Model III's could be tied together)...The company would not allow us to even speak of the ability that OS-9 could be multi-user..If a customer wanted multi-user they were steered toward the Model II/16 (for schools the Model III costing $900 per unit) at thousands of dollars and away from the TRS Coco that sold fully configured with drive for around $500 .. Also at the time Tandy was also in a death match with Apple for the school market..if they would have shown off the OS-9 capabilities they could have captured the whole school market.. Later Tandy came out with the Tandy 2000..great machine with a 80186 CPU 768K of memory unfortunately the IBM PC came out shortly after and Tandy 1200 (fully PC compatible ) shortly after that ...Tandy did not see what was coming and kept pushing their non-pc compatible's and TRS-DOS which pretty much killed the computer division by the late 1980's..
@@TheAnkMan Alas, MicroWare OS-9. If only MicroWare and Digital Research Inc would've merged. We could've had OS-9 with GEM welded together on the Atari ST and other hardware platforms.
I was working at IBM from ‘94 to ‘99 in the Personal Software Products Unit here in Buenos Aires when DOS 2000 was released. I also used DOS 2.11 when I bought my first PC! Thank you for the great video!
Yup. Stacker was a real sore point and really showed M$'s colors. But you don't get to the top by being nice unfortunately. Brings back some cool memories. Please continue the series.
It would be pretty cool if you covered FreeDOS. I've used it extensively when I had to provide support for legacy systems.
Having NO experience with that, I'd love to see that, too... would be a great learning opportunity. :)
It's really just like MS-DOS, but it's updated with a few bells and whistles. There's not much different from a user perspective, much like IBM vs MS-DOS. If you know some DOS, just start using it!
10:13 - "I can sense their excitement." - If I spent the first 22 years of my life in a sealed box, I would have been excited to get out!
Well now you can, thanks to quarantine!
I'm surprised you did not mention that PC-DOS 2000 was also available on CD, the only DOS to be released on CD-ROM.
Did it have an separate boot-floppy with "all" different weird controller-card drivers? I can imagine installing the whole thing from floppy and editing autoexec to read CD-ROM just for some additional "multimedia" support... :DDDD
I tried PC-DOS 7/2000 on a VM today, inspired by this video, and figured hey why not try the CD version? Because it's not bootable, that's why. And it certainly didn't come with a bootable diskette.
This reminds me on 1995 when I got the first PC (before I had a C64 and then Amiga). I read a lot about MS and already hated them for their business practices. Later that year I shot a copy of OS/2 and installed that on my whopping 1300 MB (that's 1.3 GB :-) ). Wasn't happy because not all MS DOS programs, especially games, didn't work on it. So I decided to get back to Windows 95. Now I didn't knew what a backup us so had no floppy to boot from. And the BIOS couldn't boot (Windows) CDs. Would had needed to buy MS DOS. But went to a computer store and asked the guy to sell me a bootable floppy. He put and empty floppy in his computer and then format c: /s I think. Took two minutes and he charged me what would be around 3 pounds. I never went to that store again.
@@TheAnkMan format a: /s
I *bought* PC-DOS 7 back in the day (at Babbages!) and it came with a boot floppy and a CD. Even back then I thought it was totally silly.
My first PC was an IBM 5170 running PC DOS 3.30. A few years later I was working at a PC repair shop when MS-DOS 5.0 was released, and the biggest issue at the time was the surprisingly large amount of software that refused to run because of the newer DOS version. A handful of software would refuse to run, then crash and lock the PC solid because the "incorrect DOS version" function was never actually tested properly. I believe one of these programs was Microsoft Windows 1.0. Microsoft included SETVER to work around that - you can see the long (and very incomplete) list of COM/EXE files it has by running the SETVER command after you've installed it in CONFIG.SYS. Also from memory SETVER.EXE was a self-modifying EXE, which even back then was a bit shifty and could trigger some antivirus programs. Fast forward a few more years to 1994 and I was running IBM's OS/2 2.0, a huge improvement over DOS, though with a lot of strange quirks of its own. I've often wondered how the PC world would've looked had Xenix took off instead. In the late '80s and early '90s the only place you'd see Xenix (or UNIX) mentioned was the odd computer magazine.
Ahh the SETVER issue! I had a friend who's family owned a 386 SX 16mhz machine back in those days. His PC originally came with MS-DOS 3.3 (even though 4.0 had been released well over a year earlier!) and when he tried to move to MS-DOS 5.0 he got stung by that issue. I think it was a piece of software his dad used that refused to run or had major issues. Anyway back to 3.3 they went until MS-DOS 6.0 was released.
I used to run a bullet-in board running on DR-DOS, it's benefit was that it was "multitasking" like Unix where you could run multiple shells. Each shell had a modem and an instance of the bullet-in board software running on it so multiple users could dial in at the same time (I think it was only ever 3-4 users at once).
DR-DOS was far better than MS-DOS, but by then it was too little, too late.
That editor is a member of a family of editors which dates back to the mid 1980s, through this is a modernized version. I first encountered it as the 'internal use only' e3 editor when I joined IBM in the 2nd half of the 1980s. The epm editor for OS/2 is another member of that family. Within IBM, this family of editors, especially the e3 editor, were extremely popular, and if you have the development tools for it (which from what I recall were not available officially outside IBM), it is a fully programmable editor, in a way similar to emacs, tho it shares no lineage with it in any way. Just the editor as distributed with pc-dos was not ground breaking, especially not in 1993 when it first got introduced, tho you'll find it deals very well with absurdly large files, stupidly long lines, etc, and does that better than even some modern editors. It is too bad the development tools for it weren't made more accessible, and released to the public, because the underlying engine is very powerfull, to todays standards, and certainly to the late 1990s standards. REXX has seen, and probably still sees widespread use on IBM mainframes.. in many ways it is the 'perl of the 1980s/90s' in that people especially used it to glue things together, transform data, etc.
Thanks for another excellent video. I used to enjoy working with DOS. I got my first PC in 1988 and it ran DOS. At the same time my employer introduced a range of electronic gauging systems, with custom software that ran in a DOS environment, so I became quite familiar with it. It went through many iterations over a number of years, and we had a few customers who refused to upgrade to new Windows-based systems until their old hardware died completely, so I was still working on these as recently as 2016, when I retired.
1:30 "IBM's new Prototype Computer" - so now, finally, it has been revealed what 'PC' really stood for !
Great episode, thank you Neil! And congratulations on reaching 100k :)
Great video, please do one for IBM OS/2 as well.. If you can't cover them all maybe for Warp 3 or Warp 4 :)
Yeah, I'd definitely love an OS/2 vid.
@QuestionMan Warp should have been The OS ! :-) Then Windows just as the gaming platform.....
I remember buying Warp 3, then Warp 4. Much more superior product to Win95. I bought version 4 from long defunct Indelible Blue. I used my student ID to get a student discount.
A fascinating look at OS history. I'd be interested in diving more into Xenix, which I had no idea existed until this video! Also, congratulations on hitting 100k subscribers!
There is an extra config.sys option, DOSDATA=UMB, that can be used to free up a wee bit more conventional memory. This is a chunk of why I like PC DOS 2000 over MS-DOS 6.22.
Congratulations on those 100k subs! I told you you're good! Proud to be part of that history :D
Thanks for the great video. Can't wait to see more from the ms, pc, DEC and DR history!
Well done, Neil. I'd love to see you jump down the DR DOS rabbit hole, as it was a favorite of mine and my friends for a spell back in the day.
I bought PC DOS 2000 and have used it ever since. Despite its little quirks, I've been very happy with it. Great Video!
the editing and content in these videos is always fantastic. keep doing what you do mate!
Thank you I will do my best
It's been many years, but I recall having compatibility issues with PC-DOS 7's memory managers in some games that worked fine on IBM-DOS 6.1 or Windows 95's DOS. On the plus side, I remember that the LH command worked with TSRs that other versions of DOS refused to touch allowing for more free conventional memory than usual.
Totally forgot about this one, and Xenix. Thanks for reminding me and the cool history.
There are some tests to do to choose your DOS version. At that ime, my favorite test was using 3DSMAX rendering a the demo car picture included. Depending the combination of OS and RAm extender (QEMM/Himem/Emm386...) the rendering time could change from 3min45s to 5min45s with the same machine (my ex 486DX2/66). The best set was MSDOS 6.0A with Himem+Emm386 from MSDos 6.2.0 edition, with the SmartDRV from Win95 SP2 !
Great documentary! thank you so much. Brings back many font memories of high school and college
Awesome having an interactive video + chat with Neil present, makes for fun KZhead. Bought you a coffee, the conversion rate from AUD to GDP is scary right now.
OMG I am actually already in the credits that was fast and is sort of surreal haha and truly my pleasure to at least also contribute 2 or 3 coffees a month for such great content so again thanks for all of the very enjoyable videos . . .

Wonderful video and presentation. Thx for that. Quite nice trip down memory lane for me.
Good look on the history of MSDOS. Thanks Neil.
Love the typeface used for the old MS logo.
Great review. A lot of nostalgia
Great video, cheers! I'd really like to see a history of Xenix. That's a fascinating story I'm sure, and as far as I know it's never been done anywhere else. Also, as I see others have mentioned already: DR-DOS! That'd be an interesting tale, and one I know almost nothing about. :) Keep being awesome, Neil.

"They were kind enough not to include any virus in the installation". That was funny.
Windows 10 unfortunately is everything a computer virus does. 😥
@@mrkitty777 start using mint, especially if you have no exotic software requirements. It really isn't that much different then windows. Not more so then osx anyway, and people have no issue switching to that. It is a little getting used to if you need to be under the hood. But ooohhh sooooo worth the week or 2 of adjusting in the long run. And don't kid ourselves, windows is never going to get any better. This is the normallity standard now, big data is big money.
@@mrkitty777 I 'always' felt MS (to be clear) Windows was the world's first computer virus. Nearly everyone got it !

Am I the only one who nearly had a heart attack when he folded over the front pages of the manual like that?
Congratulations on the 100K Subs!
Thank you
I had a Word Perfect big box to open many years ago. There were a couple of really big books in there and several floppy discs. I completed all the instructions in the tutorial. It was fun!
8:36 - folding back the cover of a "brand new" manual - makes me weep. :-(
Makes sense if you think about it! DOS was all about masochism :-)
Me too. I used to buy something new, then go down the pub and read the manual. You can't easily take a CD to the pub. If there is a CD, that is.
With yah! xD
I had the SAME thought! That's VINTANGE... AND brand new!
I'm new to your channel and your videos are very good! Have a subscriber 😀
Congrats on hitting that 100 000 mark!
I enjoyed this, and seeing one of those NetVista's dusted off and doing something. Looking forward to those future videos!
I loved PC-DOS 7. Try running Memmaker, I always found it would free up much more RAM than I could get in MS-DOS 6.22 (without third party memory managers). Someone already mentioned Dynaload which was very nice also, and the Driveparm command also came in very handy allowing me to use a 1.44MB floppy drive on an old 286 that did not support them.
Back when PC-DOS 7.0 first came out, DYNALOAD was my killer app. It let you load a device driver after bootup.
But editing config.sys and autoexec.bat and rebooting constantly until you had enough free memory was so much fun!
@@evilspoons In the Dwarf Fortress sense…
*cries in MS-DOS 6.2*
Torture with ms dos was hell 😥😮🥺
Equivalents existed for MS-DOS too. I had one back in the day, but it was really only useful once, between when you found a new driver and your next reboot. ;-)
My first computer had PC-DOS 3.3. That was a really good solid stable version. I used it for severral years, and I never found any bugs in it, which isn't something I can say for any operating system I've used since.
I find myself always checking out the amazing stuff on the shelves in the background :)
Self Indulgent Gamer me too. Saw a Close Encounters LaserDisk back there
This is a great video, thanks for all the effort making this. I have a sealed copy of the last pc dos that has ms code 5.0 and I will keep that one sealed 😂
16:05 That's not FAT32. That's HPFS, the improved file system that came with OS/2. It was largely written by Microsoft, who derived NTFS from it later on.
Great stuff. You earned a like and subscribe today.
Sitting poised for your stream Neil
Can't believe you broke the seal on the box! I'd be so tempted to leave it sealed but then I guess how would you be able to install it?! Never heard of Microsoft Xenix before now so if things had gone a different way we might not have had Windows installed on our computers nowadays.
You should cover DR-DOS next! I ended up using DR-DOS at work once to troubleshoot a massive sort machine... didn't feel like an unfamiliar version of DOS at all really.
Excellent video, the clear diction and easily understood British English is a real plus! Good that you mentioned Xenix, however more relevant attempts at giving the IBM PC a real multi-tasking O/S were made. MS DOS 4.0 was first developed inside MS as a multi-tasking, virtual console-switching version of DOS (Windows has inherited the "START" command from that era!). MS was trying to offer an alternative to IBM's own non-dedicated DOS-based MS-NET file server (a dirty hack). Every other product, MS' own and Netware required a dedicated server machine then. It was abandoned because the much bigger O/S only left 300-400K of RAM for user programs. and because of numerous compatibility issues with ill-behaved programs. Another, similar attempt was Concurrent CP/M 86, that was actually released but never took off, probably for the same reasons + licence costs as mentioned in your video.
That disclaimer for death or dismemberment makes me wonder, did they actually expect your computer to become Skynet?
Great edit and composition. The only part missing would be a small introduction to "DOS" as viewers not born of the 19xx years would not have come across this very useful thing. It did bring back many memories though. i hope you do a followup on some of the conflicts you only briefly talked about, including the big "divorce" between MS and IBM around OS/2.
Oh my god i have that exact CTX CRT Monitor! Such a satisfying power button, They are fantastic and smooth, mine still going strong! Needs a retrobrite job ;)
Oh man, that thing is the same model as the PC's we had in school. We had a brand new building when I got into year 9, which also came with hundreds and hundreds of those netvista things, in the same off white colour, with similarly early pentium 4 cpu's.
15 downvotes? Why? Am steeped in nostalgia and loved this.
Thank you for the history lesson
During these wars i used a few. MS Dos with Qemm seemed to be the way to go but then came the latest version of DR Dos with Quemm kind of built in. Then cam MS again with memmaker. these where my biggest worries, memory space. Love to see a comparison of these thing now. Also without the base memory to think about there was stacker and double space
Gotta love those classy *THICC* manuals and looking up all the goodies you could mess around with.
Great episode really helps with the fears right now Its so important for nice things to watch
Stories of the OS wars are endlessly fascinating, and you absolutely nailed this part. A request, if I may: How about a video tracing VMS->NT->Windows 10 alongside Unix->Xenix (etc.)->Linux? Under the hood, the VMS vs. Unix battle is still being fought.
there are countless things more satisfying than opening software packaging. the next DSM should include Packaging Fetish Disorder.
Xenix was bought wholesale by Santa Cruz Operation AKA SCO (who helped develop it) and rebranded to SCO Xenix in the late 80's. When I first started in IT after leaving school one of the clients of the software house I worked at used SCO Xenix as the base OS to run their Pro-IV written stock management system on. SCO also bought another brand of Unix from Berkley and sold both flavours of Unix alongside another one making three in total. SCO Unix was later rebranded SCO Openserver. They got sold to Caldera around the turn of the millenium.
Strange.... I remember an IBM 80386 network server. Running Microsoft Xenix.
I have SCO Unix original Reference User's Manual book and SCO Unix TCP/IP admin book in english, from my mother's previous work. We had it in Czecho-Slovakia after 1989. :D Also I have user/admin manual to the SCO DOS Services, Network and OS book :D
We used to mess with our teachers in the late 80s by editing autoexec.bat to restart the machine every time it booted.
R3D I edited it to display ASCII porn
I kind of miss MS-Dos. In 1993 I began volunteering as a computer specialist for a small National Park in Virginia. During my interview, I told them "I don't do Windows". They said that was fine as all their computers were DOS based. After about a year when they got their next new computer it came with Windows 3.1. Well I was stuck, so I had to learn Windows. Messy but it worked. Then Windows 95 came out and I was all giddy about the improvement over 3.1. In fact I was the second in line at my local computer store the Day 95 was first available for purchase. Over the years I've become a self taught Windows expert but I still have a number of DOS based batch files I wrote which still run on my servers.
nice travel back, I started with rll as my hd type 10 megs the size of a toaster lol
That IBM PC looks so good now, I'd swear you'd swapped it out while the camera was off! :D
Microsoft Millennium had always been and unstable OS and the MS-DOS 8.0 that was included, like the OS itself was a pain to use in more ways that one. Windows still had the shortcuts and preferences to run a DOS program and you could only boot into DOS directly via boot disk, with a few tweaks but Windows Millenniums dos version had a Protected memory program running at all times. You could not for example use programs or games that used memory extenders as they would refuse to run. Because of this and other problems a lot of people including me migrated back to Windows 98SE. The only program from Millennium I liked was the Defrag executable which I was able to copy into Windows 98 as the speed increased went up tenfold. A big shout out to RetroManCave for another interesting video, All the best Lee.
i have the monitor for that IBM in the beginning (or pretty similar) ON MY DESK RIGHT NOW . The IBM g54!! I had an IBM PC like that growing up and just had so much nostalgiaaaaaa.
Thanks!
Dos 3.30 was considered the standard when I started, I had a Bull version which had 3 manuals that I read cover to cover. Then Dos 5 and then 6.2(2). The Dos 6.2 upgrade from 6 was given for free on I think Computer Shopper - I probably still have the 3.5in disk somewhere. To be avoided were Dos 4 (buggy) and 6 (doublespace) which were the Vistas of Dos. There was an unofficial "Dos 7" based off mixing some of the 95 dos components with 6.22. Last decent MS-DOS Manual was the DOS 5 one which looks like the IBM one you have there. The 6.22 one was a lot thinner.
When I occasionally stumble across old installation floppies, especially sealed ones, I always try and make an image before anything else. So I was wondering if you also create images of the old floppy disks that come into your possession for posterity. If so, what's your workflow? Thanks. Love the channel!
Breathing in air from 1998.
From what I remember I was able to use that MS-DOS upgrade kit, which wasn't bootable on its own, on IBM DOS...
OMG that floppy disk sound... nostalgia :)
Emulated sounds probably.
Ah the memories! :)
My first 'proper' job after graduating involved using and programming on IBM mainframes. As part of that I was introduced to REXX, which I loved to use. The company then introduced PCs in the form of IBM PS2s and for some reason they opted not to install REXX! Later, the company moved away from PS2s and used good old PC clones with MS-DOS installed and we finally had more control over what application software we could have installed, which is where I discovered that a company called Mansfield did a version of REXX. I was made up that I could go back to using REXX. I always thought it a shame the language didn't catch on more as it was highly capable for writing command line driven applications.
IBM did some incircuit emulator testing to optimize the speed of PC-DOS 7. Might not be too apparent on a high end machine but it helped on the lower end machines.
I think I was actually 'certified' on MS-Dos 7 and Win 95 . Happy Days.
Should probably mention the difference between MS-DOS and PC-DOS: PC-DOS was designed to direct any calls to BASIC to the resident BASIC interpreter in the ROM of a genuine IBM computer. MS-DOS included a BASIC interpreter that had to be loaded into RAM: GW-BASIC (GW stood for "Gee Whiz", as it bridged the gap between an IBM PC and a PC-compatible clone). PC clone makers couldn't legally copy IBM's BASIC interpreter, so they left it out of their BIOS/ROM package.
DOS 2000 was, I think, the first software I ever bought as a digital download.
There is something oddly satisfying about taking off plastic wrapping or breaking a seal.
And yet, part of me is sad. (Those who know me would say I'm completely sad, but that's a different matter.)
I love this!! Yes more please! Xenix and more!
Xenix - now there's an article idea (cheers, Neil)! If you dump the contents onto you hard drive, can IBM PC DOS 7 boot Windows 95 (or even 98)? Congrats on 100K btw.
My guess is that the installation of Windows 95 retail (or even 95A) would treat PC-DOS as a previous OS at best, and allow the dual boot as it does with MS-DOS 5 or 6.x. I suspect booting into PC-DOS and typing WIN would not run it (as is the case of attempting to launch WIN from MS-DOS 6.22) but I have not verified this with PC-DOS.
I never did get into PC Dos. However back in the early 2000's I played around with DR. DOS some, but even now with any retro PC or Dos emulator I went back to MS Dos 6.22 for 486 systems, and 3.3 for 286.
100K SUBS! No one else deserves this more!
Thanks so much!
I started working at IBM in August 2000 and my work desktop PC was just like that netvista
Fantastic video as usual. Thanks a ton for the hard work producing such amazing content. The Digital Research rebranding of cp/m-86 is DR-DOS? I remember it vaguely. Can't wait for something like an OS/2 video. Quick question, where do you find boxed old software like that? I wonder if I can grab some older programming languages that were too expensive for me back then for a spin.
CP/M-86 was CP/M for Z80 ported to Intel 86 Arch. DR-Dos was DR version of MS-DOS/PC-DOS. DR lost the feature war by PC-DOS 2.0.(As Microsoft borrowed freely from Xenix tings like directories became normal in MS-DOS while CP/M-86 was flat. In addition PC-DOS and CP/M- 86 application were incompatible. While some CP/M were ported to CP/M-86 they were not optimized for it. CP/M-86 was targeted at business users. However, really go business software optimized for PC came out such as Lotus 123. DOS had more software than CP/M-86 and so DRI threw in the towel and created a DOS clone to run on the PC. DR-DOS 5.0 was better DOS than MS-DOS and second war was fought for hearts and minds of PC-Users. Using FUD fear Uncertainty and Doubt. We detect your not using MS-DOS windows might not run.
