Those were the days!
We used to ‘joke’ about a ‘gigabyte of EXPANDED MEMORY and a One Gigabyte Hard Drive as being the ultimate machine!
Windows was a ‘novel’ concept, Version 3.1.
DOS was where the REAL computer guys worked!
I even had some experience with a precursor to MS-DOS, called CP/M......................
Some of us worked in VAX/VMS, MVS, and JCL ... but that was on big(ger) iron.
Remember CP/M well. Started with 1.4 in 1976, graduated to 2.2. Wrote a “Game of Life” program in Assembler that moved the characters on the monitor, which was a DMA device, so it moved pretty quickly. Even got the screen to act as a flat representation of a globe, so if you moved off one edge of the screen, it rolled to the opposite edge and continued.
IIRC, we had 16K of memory in the initial configuration, which took up 4 slots on the S-100 bus!
Only because we couldn't afford a PDP11 as our home PC. I was actually working with HP-3000 minicomputers back then. I worked mainframes and minis years before I even saw a PC. I wanted to bring a HP3000/70 home. The heat it put off would be great during winter. Not so good during the summer.
