With a bit of hackery, mc1502 how has diskette I/O. This machine had the usual cloned MS-DOS (nee Sigma-Four DOS) and something original called OTS (One Track System), for low-memory (128K) machines. DOS runs, OTS boots but hangs.
I found some games and put them in a 720K disk (default format for this machine). Also included is the 'Immortal Player' (ip73.com) -- a kind of Action Replay for 73 games of 1980s:
ANTIX.COM, ARKANOID.COM, AV.EXE, BILLIARD.EXE, COLUMNS.EXE, DIG.EXE, GAPPER.EXE, GO-MOKU.COM, GOODY.COM, IP73.COM, KICKS.COM,
LIVING.COM, NINJA.EXE, PENTIX.EXE, PUSHER.EXE, SOKOBAN2.EXE, TET.EXE, TOWER.EXE
