It has a 10pin connecter plugging into part of an expansion connector and
another 10 line cable hard-wired to the Serial I/O card.
BTW I see by Hans list that it was manufactured in 78. Didn't realize it was
that early. Are there programs out there for it ? Could it use CP/M 2.2 ?
Were H-87 external drives commonly used on this machine ? I found the ffd
about a block away 2 wks. earlier, but someone could have taken the H-89 and
then decided they couldn't use it.
