1) A quad-height Qbus?? (Unibus?) Emulex TU03. I first
thought this
might be a SCSI controller, but a closer look indicates that it probably
isn't. This board is populated with mostly 14 and 16 pin DIPs, a couple
PALs, 40 pin DIPs, and 28 pin PROMs. My next guess would be a tape
drive interface.....
This is a TC13. A Unibus Pertec-Formatted tape controller,
emulating TS11/TU80.
2) A couple of Seagate hard drives, complete with a
power supply on a
mounting channel. These are labelled: Equipment No.: PA4B2A, and on the
drive itself: 975002-001. What are these?? I'm pretty sure there not
SCSI, but other than that, I'm puzzled....
What sort of connector? If a 60-pin and a 26-pin, then they're SMD.
The "9750" part of the part number sounds like a CDC part number -
Seagate bought out CDC's disk drive business many years ago.
