-00_4041_sysCtlrOper_Jul82.pdf
as always, if folks have other manuals that I could borrow to scan, I'm
happy to
put the results up on bitsavers.
That will be an interesting story to hear.
However, I am not going to make a trip from The Netherlands ...
will some sort of transcript be available afterwards?

That distribution board has a connector labeled RX50. The RQDX3 has a 50 pin
cable that goes to that disti board and from there you should have the usual
rats nest of 34pin (floppy), and 40/26pin (hard disks) from the distibrution
board to drives.
While your in there check the fans!

Ack, it's been a while since I've had to play with the disks. Thats a problem
with VAXen the keep running and cases stay on. Seriously the last time I was
in my uVAXII was four years ago to replay the TOY Clock battery. So as a
consequence I forget actual number of wires in the MFM disk cables. After all
it's only important if a disk dies.
