Thanks for the useful information about the memory. I have already managed
to locate 1 pair of SIMMs on Ebay. I will continue until maxed out.

I see how to hook up vt220 with db25 f-f null modem cable, but how does that
get vt420 hooked up? It appears to have some kind of RJ connecton in back,
not DB style. Is there a special cable for that?

Where do they hook up to? I see on ebay cables with db15 end and 3 bnc,
keyboard and mouse at the other end. I hook this into back of DEC 3000 where
it has tablet port? or do I need two separate cables, one for monitor from
3w3 connector and one from tablet port for keyboard and mouse?

I have plenty of monitors, but not quite sure what you are saying. Say I
have monitor with 13w3 connector on back, then I need 3w3 to 13w3 cable and
monitor is set? Where do keyboard and mouse come into picture? Special cable
plugging into tablet port (DB15) in back of DEC 3000?

Sorry for so many questions, but I do not know too much about these machines
(as if that is not obvious). Still I hope to soon have OpenVMS or Linux
running on them.
