The system had a floppy disk controller that could

The Z100 Lifeline or some such site has info on an
IDE card that's custom to the Z100 and 120 I guess. I
can dig out the specific URL if anyone can't find it.
Video came from a dedicated video board that was,
for it's time, quite
sophisticated (the PC had nothing better until the
EGA cards came out). It
was pure bit-mapped color graphics, 640x225
resolution.
Woa not true. The Sanyo MBC-550/555 had, IINM, 640 x
240 x 16 or something. I could be wrong on that
specific item though. There was talk of the Tandy 1000
having over 200 lines of resolution, but it took
tricks to access the modes (maybe it wasn't really
talk, just drivel LOL). There were many a
pseudo-compatible that had 640 x 400 x 8, like the
TRS-80 model 2000. There were aftermarket cards like
the Sigma 400, Persyst BOB, others, that gave a
vanilla pc 400 lines of res in color modes.
