This is getting to be a real trip down memory lane.
Radio Shack TRS-80??
My first PC was an IBM clone back in 1986, with a 20MB HDD, and 512K (Yes, 512 KILOBYTES) RAM, an 8086 4 MHz CPU ("Turbo" mode threw it into 8MHz), and DOS 3.0 . . . I think that was the one you were referring to Rick as "pure awesome". I actually did some programming on it in Basic (not anything sophisticated by today's standards). Then came 286 processors, then 386 processors, and you could get them with a separate math coprocessor.
QBasic came along there somewhere. And then Windows 3.1, the first GUI (well . . . not the first . . . I think there were Windows iterations before that, but they were very unstable. 3.1 for Workgroups was the first iteration that achieved any widespread use).
And Zenith I think it was had achieved a GUI first, that Apple later "pirated".
Speaking of 1976, Rick, I think that was when Apple came out with a rudimentary "personal computer", just a keyboard I think. And in 1976 I was doing graduate research in physical chemistry with a PDP-12 computer in Assembly language.
Fast forward . . . in 1988 I had a Zenith 286 laptop . . . that thing weighed a ton.
That was all command line stuff. I still have my 8086 machine stashed in the junk room that we all have . . . plus a book on DOS commands. I think I paid over $1200 dollars for it. Has a monochrome "12 amber monitor. The big thing then was color monitors.
I think before QDOS there was CPM, which was the predecessor to DOS.
Yes, I remember those machines with dual floppies. As I recall, they had NO HDD, and you had to constantly swap out one of the floppies when you needed a command that wasn't on the one in there.
When that Y2K faux crisis happened, a lot of institutions had to hire retired Fortran and Cobol programmers because their data and programs had been coded in those old languages. Some retired guys came out of retirement for a pretty hefty wage.
Wow . . . there's more, but right now my memory banks are overloaded. Rick . . . ?
