Ahh! I thought mail'd died here, so I reset the machine.

It died, same failure. Got tired of toggling it in and failing every
time. I plan to burn it on a ROM and stick it in in place of the RX boot
rom. (I already had it, and assumed I was toggling it in wrong.
I don't think so. Are all the cables "black" cables? If so, it ought to
work.
Yes.
Given that you're getting a BUS ERR, I'm willing to bet that you don't
have bus continuity done up right. Which slots are the UDA50 cards in?
What are in the other slots? Which slots have the NPR jumpers removed?
Oh, crud. The UDA is in slots 14 and 15. There are 18 slots, as follows:
1 M8266
2 M8265
3 M8267
4 M9312 + M7859
5 M7891
6 GCJ
7 M8256
8 GCJ
9 M7856
10 M9202 + GCJ
11 M7819
12 M7819
13 GCJ
14 M7486
15 M7485
16 GCJ
17 Tape controller (Non-DEC)
18 M9302 + GCJ
Once you do get it working, the RT-11 BOOT command
only will boot
up other RT-11 volumes. BOOT/FOR is supposed to boot other (foreign)
OS's. What OS is on this RA drive that you're trying to boot?
RSTS/E (It came from the 44)
