I'd be interested .... Did the 8032 PETs use them? How many do they have?

I was surprised to find a local supplier clearing old stock of 2112 RAMs. This is an NMOS static RAM 256bit x 4. The chips are new, labelled SY2112-A (Synertek I think) and they're supposedly 350 nS devices. I believe this was the chip used in late-model Commodore PETs (after they designed out the earlier 6550 chips); maybe someone wants to confirm this for the list. I seem to recall the Heathkit micro trainer used a couple too, but I could be mis-remembering. Not as commonly needed as the 2102 or 2114 I know, but if anybody wants some I could pick them up. They're 5 for a buck, plus whatever it costs to mail them-- unless of course you want to offer me something extra for my trouble :) -- Arlen Michaels arlen.michaels(a)sympatico.ca

... I could use some 2114's and C2109-4's. These are used in Teraks for Video memory and System memory. Just in case anyone knows of a source ;) -Lawrence LeMay lemay(a)cs.umn.edu
