My first IBM machine (first I used - the first computer I actually personally *owned* wasn't till this century) was an Epson XT-compatible. We had GW-BASIC and Q-BASIC, and a much superior form of DEBUG.EXE that came with, get this, an inbuilt mini-assembler! Yes, I could do this: -a xxxx:0100 mov ah,09 xxxx:0102 mov dx,0109 xxxx:0105 int 21 xxxx:0107 int 20 xxxx:0109 db "Hello, world!",13,10,24 And it'd produce the appropriate bytes. From memory, that would be B4 09 BA 09 01 CD 21 CD 20, followed by the text string. I actually used that to write seriously-useful programs, like one that helped us keep track of which treasures we'd picked up in Colossal Caves. (For some definition of "seriously-useful", anyway.) > At IBM we were coding Rexx on the VM370 systems, and then Rexx on the > OS/2 systems; no python, and nothing much else either , oh yes, Turbo BASIC, > Visual BASIC, and of course BASICA although you could then get it as GWBASIC, > ... still no python. I wasn't working at IBM itself, but when Dad switched to OS/2 for our home business, we switched too. That would have been about 1992; we used OS/2 2.1 briefly, but got properly into things with Warp 3 (Connect, and I can never remember whether it was red-box or blue-box - we had the one that came with a Windows license for Win-OS/2). Ooh, we had the most amazing fun with that... we set up, to quote my older brother, our very own personal World Wide Web! (Not very accurate, but that was the big buzz-word at the time, and hey, we did have a LAN.) And over the ensuing years, we got to know which network cards were the most reliable - mainly the Realtek ones, we had some RTL8029 cards that went into so many different computers - and if anything went wrong with drivers or anything, I'd pop the case and stick in one of my stand-bys. Either that, or we'd go search for the drivers on Hobbes, and either download 'em onto a floppy disk or LinkWiz them across - because one of the very first things we'd put onto any computer was the comms software that uses a special serial-port or parallel-port cable to transfer files. Immensely useful, until generic network drivers got better :) > Did anyone mention that PCs back in that day were toys. And I do mean toys. > They were slow, they crashed, their graphics sucked... Oh no! No no no! Graphics didn't suck for everyone. Maybe they did for you, you with the horrible CGA card plugged into your TV. Maybe they did for the people who used the default IBM Monochrome card that didn't do graphics at all. But no, my dad was forward-looking. He got the best. He got a Hercules Graphics Card, capable of driving the same screens the IBM Mono would, but giving us the tremendous capability of 720x348 monochrome graphics! It was awesome! Plus, for text colors we had black, white, bold black, and bold white, and - get this - underlined! Nobody else got that. Yes, those were the days.
