I don't think anyone had GB of anything back in the 80's. I remember back then when our IBM mainframe was upgraded to 1mb of core memory and that was serving 3 hospitals with 100's of terminals.
When I first started working at Software Results in the Fall of 1984, me and one of the other student workers were marveling at the 32-bitness of the VAX-11/750 (with 8MB of physical RAM in a 4GB virtual address space) and trying to envision how expensive and how large *Four Gigabytes* of RAM would be, and it was *immense*.
This same machine (8MB RAM) could handle 70 dumb terminal users, but to be fair, it did swap a bit over 40 users. The two fattest apps we had were were VMS MAIL and MASS-11 (word processing).
I will take this opportunity to point out that that model has a clock speed of 3.125MHz. This is what efficient design is all about. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
