Trivia question : What feature was present on all disk
based M1s (in
fact any M1 with an expansion
interface) but not on any M3 or M4 machines?
composite video out. I used that, a LOT for classroom lectures, etc.
1771 FDC
dual cassette port?
or unreliability of model 1 power supply?
or flaky interface between "cpu" and EI?
model 1 expansion bus
"ability to ignore" some model 3 I/O ports?
There are a lot of differences. MOSTLY minor (mostly harmless?)
as to which ones are "features", . . .
