I have a GSRam with a meg on it. I would like to get a GSRam+ with
considerably more. I also have an Apple II Memory expansion card
(circa 1985) which is suitable for use in standard slots (not aux/memory).
My question: Will the chips from the GSRam work in the Memory Exp. card?
I know they are the same size (32K per chip), and that the memexp chips
won't work in the GSRam (too slow), but I can't find anything in the
included documentation for either that would tell me if they're compatible.
Does anyone know if this would work?

Mine's full). They aren't 32K per chip, unless the universe just inverted and you can say that 256K*1 = 32*8. -- unknown@ucscb.ucsc.edu

Note that the chips are 256Kbitx1 (not byte). So, if you take 256x1024/8, you do indeed get 32K per chip. And now, a question! (Q) The AE gsRAM manual I have seems to imply that one could plug in single chips into the board with no problem...fact or fiction?

You need 8 BITS TO MAKE UP A BYTE.....hence 8 chip sets yield 256K BYTES. ============================================================================= | Chris Shatara | Internet: shatara@memit.enet.dec.com | | Opinions expressed are | DEC Easynet: memit::shatara | | mine and mine only! | UUCP: ...!decwrl!memit!shatara | =============================================================================
