I got the system as a whole. Everything came from the same person, except
for the LA120, which I bought refurbished from a local dealer. I think the
communications settings have to be correct, because I get the register
printout, and when I send an ASCII character to the LA120 through the
programmer's console, it prints out correctly. I'm not sure I have all the
right packs mounted, because A) I only have 2 of the 3 drives connected, and
B) the labels on a lot of the packs are faded, or have come off completely.
The RSX-11M version is 3.1. The system has 8 (I think) additional serial
lines. I have lots of software manuals, but other than the processor
handbook, I have no hardware documentation. How many RL01 packs does an
average RSX-11M installation use? Also - do the drive numbers (0,1,2...)
depend soley on the order they are connected in?
