Okay, I just opened up another box (a MVII in a BA123)
and found that
it contains a SCD-RQD11-EC controller. I believe this is an ESDI
controller with onboard boot ROM. This ought to work but since it
came out of a MicroVAX, I'm assuming that the boot ROM will only work
on a VAX. Is that correct? Or is there both PDP-11 and VAX code in
the ROM? Also, I can't find a manual for this board. Manx doesnt have
it and Bitsavers has a manual for the RQD11-ECPlus but that doesn't
seem to match the board layout of my board so I can't use it to
determine the switch settings. Anyone have documentation on this board?
Ok, now you're in luck. The SCD-RQD11-EC will work with the KDJ11-A
and your Maxtor EXT 4380 ESDI drive.
I couldn't find the manual either, but extrapolated enough out of the
RQD11-ECPlus manual to figure out how to configure it. The onboard
"WOMBAT" utilities will let you format the drive and boot the drive,
and will run on the PDP-11. The controller also has cache on board,
maybe 512MB, I forget without checking.
I have some notes on the switch settings to enable the ROM and set the
addresses. I'll dig those out tonight.
