Still have no idea what that means…

Not bad, but I like this one better: https://arstechnica.com/gadgets/2017/06/ibm-pc-history-part-... And specifically for the IBM choosing Microsoft: https://nemanjatrifunovic.subs…

Actually it was released in 1989. People’s memories are a funny thing…

The worst OS except for all the others.

You are describing MS-DOS. As article states, this used DRI's Concurrent DOS, which was basically rebranded MP/M-86 with a basic MS-DOS compatibility layer. More about Concurrent D…

I like it! Is it still being produced given that Z80 has been discontinued?

This is the book to read if you are interested in the topic: https://www.goodreads.com/en/book/show/44882.Code

Roman Empire did not "ceased to be" in 476; all it happened that year was that an usurper was deposed.

By now, the dude must have developed something ridiculously successful and got filthy rich /s

Or concurrent cp/m?

GEM ran on MSDOS and GEMDOS

Ditto. Metro was the best graphic UI I ever used. I liked even on the laptop.

Right. I am saying there is a difference between portable and non portable assembly code. If you interacted with the machine via call 05h interface, it was portable. If you accesse…

In 1981, one could write a z80 assembly program for cp/m and it would run on thousands of different computer models.

Time to switch to PL/I

Gary Kildall was unable to understand why IBM insisted on using a simplistic CP/M clone, when DRI had a multitasking operating system in 1979. The PC industry just didn’t care.

That's exactly what's happening. Many claim they are more productive with AI, but individual rise in productivity just doesn't translate to projects being completed any sooner. And…

There was a rumor of MS and DRI having a non-aggression pact before 1981: https://nemanjatrifunovic.substack.com/p/gary-kildall-bill-g...

Back in 1998, that would have been a legitimate concern…

They developed something called M-DOS or MIDAS in 1979, but by that time CP/M was already established, so they decided against releasing it.

That dude needs to fix his shift key. That aside, the job market has been horrible for recent graduates in the last three years and it’s just a fact.
