Apple RAM Expansion in the IIc Plus?

[KG7PFS]

I've read that the Apple RAM expantion for the IIc is not compatible with the IIc Plus. Is that true? Is there an easy way to fix it? I just ordered one and I need to know witch "c" to put it in.

I don't claim to be an expert on this, but I have a IIc and IIc Plus. From what I understand, a ROM 255 or 0 IIc can't use a memory expansion. If you have a ROM 3 or 4 IIc then I think you are good.  I purchased an expansion from a2heaven for my IIc then realized it was not the proper ROM level to use it, so I installed it in my IIc Plus!

From my experimenting with RAM cards, only the RAM Express works with the IIc+.  ZRAM 2 and 3 do not work with the IIc+, but works with the Iic's with expansion port.

Ah yes, that's what I bought for my II c before realizing it would not work in my II c due to the firmware revision.

So OP, I guess it depends on which memory expansion card you have. I'd also check the ROM revision as well.
