I think a
Floppy chip with a real built in data separator is the way to go.
Find a37c65 or 9266. no big deal using raw ttl as then you can do ANY
data rate. Also a good
dma is needed, as having the cpu do floppy I/O leaves
no margin for serial I/O.
Not required. Small system, nice addition but pumps up complexity
more than a bit. The other thing
is a NICE terminal to go with the system. I don't want
to boot windows or dos to run a terminal. For development work a PC is
a good idea until you get a OS running. I have a used Altos IV here,
from what the keyboard says but I don't know of how many years of
life the terminal may have left.
Fix it, build one or find a VT220,320,320 whatever.
