Does anybody out there know if the new 4mb RAM SIMMS can be used in a mac plus? I'd sure like to have 16 meg in my machine... Either thator I'll buy a IIcx (yeah,right!). Brad Koehn UW-Madison "Fly like an Emu!"

No, nor are they useable in a MacSE, and I don't belive they will work
with a regular MacII - they will work, however, in the SE30 and IIcx..
I'm not sure about the IIx. Hope that helps.

Hope that helps. >Geoff. The mutant 4 Meg SIMMs will work in a IIx, but probably not in the other two (SEx and IIcx) due to size limitations. By mutant, I mean "piggyback" or whatnot. The "normal" 4 Meg SIMMS ought to work in all three. This was discussed over the net a little while back. --- Alex UUCP: {att,backbones}!ucbvax!qal.berkeley.edu!lauac INTERNET: lauac%qal.berkeley.edu@ucbvax.berkeley.edu

Correct me if I'm wrong, but I seems to remember that the maximum
amount of RAM that can be used in a Plus or SE is 4Meg, regardless of
the chip density. The ROM addresses start at 4Meg, consequently, you
cant put any RAM there. I don't know if the denser chips would work
or not, but in any case you cant have more than 4Meg.
