Thanks Bill and Tim, this gives me some idea.


I might actually be able to get a SBI backplane assembly
from an 11/785 otherwise in not so good shape (Will?) But
I'm not sure I can get the LSI-11 console computer of a
11/785. So it sounds like I need just one additional
RAM board for the LSI-11? Does that have a product code
or number that I could ask or whatch out for? Would it
come from a second LSI-11 (e.g., being just another
memory board of the same kind?)

The software and microcode may end up being more headache.
First I hope I will get any RX01 disk drive to begin with.
Then where to get the software from? Could it be copied
from an existing 11/785 that someone else might have?

thanks,
-Gunther
