Can anyone tell me the part numbers for the cable and breakout panel
for the RQDX3 that allows it to be plugged into an RDxx MFM drive and
an RX50 floppy drive? My understanding is that there is a ribbon
cable that connects the RQDX3 module to some sort of panel that has
places to plug in the cables that connect to the drives. I think the
RDxx drive just uses standard PC type cables between the drive and
this panel. Is that correct? Anyone know the part numbers for these
parts?
I dont have the box with all the board and cables so it's all from memory.
It carries a 50-class part number for BA23 boxes (mounted at the rear wall
of the drive cavity) it's breaks the 50pin out to a floppy (rx50 or 33)
and one drive (RDxx). Th board is only three or 4 connectors and nothing
else so if you find the schematic you could make it easily.
For the BA123 it an M9058 which looks like a Qbus board (it is) and it
breaks the 50pin out to the mix of up to 4 drives(RDxx) and a floppy
(RX50 or 33). The cables are 50pin IDC and the drive cables are 34 for
floppy and hard disk and a narrow (22 or 26 pin) for the hard disk.
The cables are nothing special (no PC half twists). The M9058 requires
5V power off the Qbus.
