Very cool. I only have a PDP-11/73 in my personal collection (not currently
booting), but an 11/20 and 11/34 are right down the street. Someday (maybe
soon) I'll get those fired up again.
As for memory, I hope you are aware that RSX reports memory in kilowords,

Doh...! No, I wasn't aware of that. In which case, SYSGEN apparently had no
problem detecting how much RAM was in the system! Thanks for that tidbit.
But anyway, why not go for a fully loaded machine when you have the chance?

Well, I suppose if it's as easy as changing the config file and re-running
SYSGEN, I'll do it.
I'll check out that documentation pronto (Intro to RSX sounds like a great
start). Right now, I've been working on punched card reading on the PDP-8,
as well as emulating a VC8E. Sounds like I need to catch up on the 16-bit
realm for a change!
