Good times of the old CPM/80 I used on my Brazilian clone of "Apple//e" in 1990. MBasic, dBase2 was complex for a kid but with the help of some books I was able to learn a few things. This PIP command is very powerful for copying data segments between devices, memory, disk, etc. What became obvious is the superiority of MSDos and especially PC/Dos in its time. Whoever said Unix is difficult never had to deal with the limitations of CPM! Good job.
Hi, thanks for this blast from the past. Back in the eighties I used CP/M (v2.2) on a Z80-based computer. An important difference between CP/M and MSDOS is that CP/M came with a special adapted BIOS for every computer model, while DOS relied on the BIOS provided by the ROM on the motherboard. Programs for CP/M were supposed to call into the BIOS for all I/O-operations (for instance writing to the console). This made those programs portable between different hardware, but had a huge negative impact on performance. For instance, browsing through a document in Wordstar was unacceptable slow. However, I stumbled upon a posting by someone who had figured out how to modify the Wordstar binary to make it write to the console directly. I applied his solution to my Wordstar binary using a hex editor. This improved the performance enormously, probably 10 times as fast. So be careful blaming the languages/compilers for the bad performance. I remember Turbo Pascal to be blistering fast, as long as you didn't do any I/O. If CP/M 86 used the same BIOS construction, i t's probably this BIOS which is to blame.
Interesting information. I'm really not sure how the BIOS calls are implemented for x86 CPM. I imagine that they hook into the PC bios at some point, but there's probably an inefficient layer in between.
The innovation of CP/M was the separation of what we would call the 'DOS' now from the BIOS. The BDOS abstracted the differences at the hardware level so the the CP/M kernel could run. This was (probably) technically copied from concepts in RSX-11M (Dave Cutler) used to this day in Windows as (HAL - Hardware Abstraction Layer). CP/M's problem was that there really was no standard disk drive manufacturer or format until IBM came along and said 360k would be a standard. Everything in Wintel history follows from there.
CP/M-80 expanded the world of "shrink wrapped" applications for business, engineering, science and much more. It attracted the attention of programmers who produced robust & reliable products that got the job done.
I have never seen CP/M before this, but was aware of some of the crossover with DOS. To this day we can see CP/M influence even (distantly) on modern OSs. I was impressed to see the text based pseudo-GUI utilities built in. Reminded me of the Amstrad PCWs. I started with MS DOS 3.3 and I don't recall it had much at all beyond command line tools until v5. I was less impressed when I saw "ed" though, because I was taken back to the bad old days of DOS Edlin lol. Was left wondering if the "print" command can print to the screen and not just to a printer.
I ran the analyst position doing all the multi-million dollar budget for the Xerox Portland, Oregon district office on a Xerox 820-II running CP/M and dBaseII from 1984 to 1991.
CP/M was innovative in many ways, both in concept and as a commercial product. CP/M 86 was way too late in the game to offer any real challenge to MS-DOS, but most of what it achieved, in time, was due to its CP/M "inspiration". CP/M 80 was certainly a product that shaped expectations and it made an impact on some computer enthusiasts in the 80s or even much after CP/M was obsolete, as was in my case. I considered CP/M to be the "missing link" in micro-computing evolution, since what started from hobbyists ended up in the mainstream.
Our telco engineering dept got a Dec Rainbow with our first hard drive, 5megs. We had DOS-1 and CPM-86 both installed with plenty of space. My experience was that CPM-86 was better; you could have "users" that give you at least a way of organizing files. When DOS-2 came out with directories, it just blew CPM away. (I hope I remember all this correctly, it was a long time ago).
Cp/m 86 would have been as successful as cp/m on 8 bit computers was if IBM didn't decide to price it almost 10 times more than the equivalent PC DOS, written by Tim Patterson, which was more or less an obvious copy of CP/M. It used the same routines, same BIOS calls, almost the same API. PC DOS 2.0 was the first really substantially different OS, with a tremendous amount of changes (from API to disk access, file system and such). While no one can deny that MS did incredible things for the computer world, it was Gary Kildall who kick started it all. He was the real visionary, and by all accounts a really good and genuine person.
MS-DOS v1 was call compatible with CP/M 2.2, the 8-bit version you can still play with MSX-DOS v1 (MSX-DOS v2 is not CP/M compatible) where you can run generic CP/M (Z80/8080) compiled (.COM) programs (not machine specific -ie. no key or display specific stuff). Deleted files should appear in USER7 or USER15. Later CP/M 3 introduced the first (GSX) graphics extensions, which Concurrent DOS (CP/M 386) included.
In the early 80s, my dad had a Kaypro 2 for work. One of the first computers I ever used. Since it had the ability to print, which I couldn't do from my Commodore 64, I wrote a bunch of my school papers on it using Wordstar. At the time, I was just blown away by how cool that machine was and spent many hours carefully tinkering on it (since I knew my dad needed it for work).
I think I recall using WordStar on the Kaypro 2 at my dad's work too. I don't know if I ever printed anything or not, and we had a manual and eventually electronic typewriter at home, so probably I did school assignments on that. However I remember being pretty creative with excuses for not finishing these, so maybe I wrote up the excuses on the typewriter instead. :-)
@@PCRetroTech Staring by about 1982 when I was about 12, if I could do it using a computer, I wanted to. A related story...

I wrote my first paper using it and then realized... I didn't have a printer and I couldn't figure out how to use my dad's work's printers on the C64. So I re-typed it into WordStar so I could print it. His work had a really nice Impact Printer, which looked amazing compared to dot matrix (especially at the time).

Beautiful memories.... CP/M was very fast, stable and efficient. In fact I preferred it to MS-DOS for many years. I fondly remember how it with a Z-80 processor easily outperformed far more recent MS-DOS PC-XT's and even 8086 machines.
Have you considered getting an Amstrad PC1512/1640? The supplied Dos Plus installed on them will run CP/M-86 applications as well as many MS-DOS applications. It is the operating system which sits between CP/M-86 and DR-DOS and it can read/write both CP/M formatted disks and MS-DOS formatted disks. If the PC has a NEC V20/30 CPU, it is possible to run some CP/M-80 applications using utilities such as VCPM.
The game was already carted down... by Mr. Gate's mother playing cards with the IBM CEO... just ibn case somebody tells you that little Billy had no help and only $100 from Daddy.....
On the day IBM showed up at his door, he was out playing with his private plane, instead of working. "Assaulted in a bathroom" , that's an Urban Legend ... He crashed in his plane, and he had issues with alcohol.
It was Gary Kildall and his wife’s fault. When IBM came to purchase CP/M for the PC, they wouldn’t sign the non-disclosure agreement IBM pulled out so they went to Microsoft and asked them if they could supply an operating system. The rest is history.
@@JS-fe8sx Kildall never had the brutal capitalist instincts that Gates had. He would have been outmaneuvered sooner or later no matter what happened or how good his software was.

I remember CP/M. ED was horrible; the MS-DOS EDLIN was functionally the same thing, and I loathed that too. At the time text editors were rare to nonexistent, and word processors (that could run in text-only mode) were $500 plus in mid-80s money. I also remember when Turbo Pascal* came out for MS-DOS. I quickly adapted it as a text editor. Like it or not, MS-DOS was destined to come out on top, mainly because that's what the PC came bundled with. Digital Research came out with DR-DOS, which was binary compatible with MS-DOS, and usually offered superior features. DR actually developed multi-user multi-tasking versions of their DOS, but the IBM/Microsoft juggernaut had gained too much momentum by then. *Software was hideously expensive back then. Prices of $500+ were normal. Borland's Turbo Pascal was revolutionary because they charged only $60 per copy, and compile times were blazing fast for the time. Copy protection was rife, and made unstable software even less trustworthy.
This video was very briefly shown in a Techquickie (Linus Tech Tips) video "The CPUs You've NEVER Heard Of", published yesterday. Spoiler alert, they are CPUs you will have heard of. :P
That's quite funny. Yeah I've heard of all those. They actually could probably have found CPUs I haven't heard of. Disappointment! Anyway, thanks for the heads up.
Was there more to the setup than showed here? I seem to remember MS DOS setup was a fair bit more complicated (like specifying the hard drive specs, port addresses, resources and such)
Technically, I have computers which can run DOS.. but the closest thing I'm still running is Windows 10... but I do still run CP/M on a C128 every so often. Actually, helping out a bit with finally getting proper HDD support for that CP/M version.
Rather than pushed out by MSDOS, CP/M was mainly pushed out by IBM, introducing its PC with three optional operating systems to choose from, pricing CP/M 6x higher than "PC DOS" (MS DOS). Whether IBM did this in collusion with Gates, who knows, but most of the damage was done by IBM. On the other hand, i dont know what would have prevented Digital Research from offering a lower priced copy of their OS for the PC if ordered directly through them. Did IBM prevent that? Its as if IBM execs were deliberate about not using DR, and missed out on what would have been a great long term collaberation. Arguably that karma caught up with them as they too lost market share, trying to write their own OS after parting with MS. IBM could have had a Windows GUI (GEM) to rival Apple much earlier.
Everything back then was "6 to 8 weeks to arrive", and they meant it. The bad old days. That's why mail order options weren't really a viable business strategy back then.
