I used to run CP/M
I ran it on: A Tandy Model III with a 5Mb Hard drive, A Kaypro Model 2 and a Model 4 And on a Ferguson Bigboard with Two 8" Shugart floppy drives and a 10 MB HD It was amazing what we could do in 64K of ram |

Sure. I worked tech support for two different Kaypro dealers in 1982 and 1983. We had the Kaypro 2 and the Kaypro 10 with the 10MB full height 5 1/4" drive. I wrote a bunch of different mailing list software for it using dBase II.
We also experimented earlier with the Microsoft Z80 Softcard (https://en.wikipedia.org/wiki/Z-80_SoftCard) but no business we knew actually used it so nothing shipped. Later on, I did contract work for a company that did software for the Commodore C128 including the CP/M side of it (https://en.wikipedia.org/wiki/Commodore_128) yes that was quite a while ago. |

Quoted: I forgot about the Osborne I had one for a short while with a very small screen Quoted: Quoted: Osborne1 and Osborne1. ca. 1988-89. Staring at that little 7"? CRT I forgot about the Osborne I had one for a short while with a very small screen Yeah, I worked on one of those for a while in '82 or '83, writing an interpreter in COBOL for a financial reporting language. Now I work on two 28" monitors and it's barely enough. The tiny screen was OK for what I was doing, but it was a hassle when I needed to Google something about COBOL syntax. And forget about tethering to my smart phone as a mobile hotspot. I don't think I ever got that to work. |

there was no native CP/M for the 6502; you needed a 3rd party Z80 card of some type with an 8080 or 8086 in order to run CP/M. ar-jedi Quoted:

I used to run CP/M It was amazing what we could do in 64K of ram <raises hand> some rocket scientist programmer at Boeing CAG wrote an entire system for instrumenting and translating acoustic defect analysis of carbon fiber composite materials -- in CP/M, using a mix of pascal and assembly. i spent a lot of time in undergrad working on material characterization for the 777 program (read: slave labor to a team of professors and PhD candidates) and i learned WAY too much about how that analysis system functioned. i also spent a lot of time trying to figure out some problem with it, any problem, so i could gain notoriety by pointing and saying, "look right there, it says X, it should be Y -- i am a hero!". that day never came.

When I was in High School my father had a DEC Rainbow 100 with dual processors - had an 8088 AND a Z80 so you could run MS-DOS or CP/M. Took it to college my freshman year and used it as a dumb terminal (had a 300 baud acoustic modem) for doing my FORTRAN programming.

Quoted: Quoted: Trash 80 Model III, my mother ran a word processing business off of it. That's gotta be the most extreme example of a business with a limited window of viability I've ever seen... No, she was good at that, a later business was editing and burning CD's, when the burners were several thousand dollars and there wasn't good consumer software to lay the data out :-) |

I ran CP/M on my Commodore 128 in college. Wrote many a paper in Wordstar. I miss the simplicity of text editing in it. Come to think of it, I'd pay to have a version of Wordstar in a current OS. I wonder if they have that already? http://wordtsar.ca/
