Thanks for the help (to you and everyone else who chimed in!) -- I wired 
it up and plugged it in and it came to life quite nicely!  All 
self-tests pass as evidenced by the below photo:

Looks like I'll invest in a 240V outlet or two.  Can't wait to get it to 
do something useful (for some definition of 'useful'); I'm in the 
process of getting the software tapes archived (thanks to the help of a 
local QIC expert) but once that's done...

Thanks again,
