This...does not agree with the reality I find upon opening up the first
HP-IB disk that came to hand (a 7958). The HP-IB connector is soldered
to a board which speaks to the disk drive - a Micropolis 1355, not a
TManything - over two ribbon cables. Except for stuff internal to the
1355, the only other PCB in the box is the power supply.
