on 02026-02-16Xerox introduced its own #CPM machine in 01981, based on the Ferguson Big Board. #history
on 02025-09-02First Osborne Group library disks for #CPM #retrocomputing, including #games, printer drivers, example Pascal code, dBase II programs, an outliner called TOUR, assemblers and disassemblers, Supercalc spreadsheets, etc. From 01985 to 01991.

on 02024-09-04CP/M eventually added more features to its #filesystem. #retrocomputing #CPM
on 02024-09-04The CP/M #filesystem structure has one 32-byte directory entry for each “extent” of up to 16 kibibytes, allocated in units of 1024 bytes or more. #retrocomputing #CPM
