The CP/M machines bring back different memories, using
that and BDS
C because an 11/780 with 4MB of ram and 40 users meant each user was
getting 1KB so it swapped and swapped and swapped.
4 MB RAM and 40 users works out to 100 KB of RAM per user for me. Even
accounting for a large at the time OS it should be several tens of
kilobytes per user on average for actual useful data. So, because
there's probably some detail here that means you're right and I'm
wrong, how do you arrive at the figure 1 KB of RAM per user in that
scenario?
