Subject: MPM vs. CPM

MPM-816 is NOT the same thing as CPM-816; the former is MP/M (multi-user),
the latter is CP/M (single user). You are correct that MPM-816 does include
a cache for the hard disk (64K) that is automatically flushed every 30
seconds. G&G has invested most of their effort in this product rather than
any single user os - a new version of MPM-816 is due out momentarily.
