Subject: Qbus RL02 controller

Does anyone know of companies (preferably in Canada) which repair old
DEC boards? I have an M8013 RLV11 Disk Control Board which gives solid fault
lights on all my RL02 drives. Also, is there some fatal incompatibility between
this board and the Micro PDP 11/73 bus? This board first failed when I tried
it in the '73. It had been running fine in an 11/23 beforehand. Of course, it
may have been killed in transit by static or something; I wasn't particularly
careful with it. I have transferred other devices between the '23 and '73 (a
QD01 disk controller and an RX02 floppy controller) without problems. Still,
I want to be sure that I don't get the board repaired only to have it blow up
when I put it in the '73 again. Any help?

John, no sig

The RLV11 is a two-board set that speak to each other over the CD Interconnect.
If you take the board that the drives connect to and plug it into a slot in
the Micro PDP backplane other than the first 3, you put +12 into a bunch of
logic.

I know, I did it.
