processor in MX80 is 8085 I think. One of
the 8080 compatible CPU's.
inside: CPU, ROM, RAM buffer
CPU runs ROM code, takes data
from connector, puts it in RAM buffer.
It moves steppers (no position feedback,
just moves the motors X ammount of steps)
and punches the correct pin(s) on the
print head.
