The RAM EXPRESS card is 100% compatible with IIC Plus.

: Most Apple IIc+,s and IIc's have 128K of RAM in two 64K banks. Use
: AppleWorks, modified to recognise extra RAM, to check if your IIc+
: has any more than the standard 128K.

: The Apple IIc+ runs at about 3.6 Mhz. This has two consequences: first
: it messes-up Apple's (1 Meg) memory expansion card, and secondly you
: cannot speed-up a IIc+ with an 8 Meg ZIP-chip or a 10 Meg RocketChip.
: (You can speed-up an ordinary IIc with these little miracles.)

: The IIc+ has a "memory expansion" socket like an enhanced-type IIc,
: but Apple (brand) IIc RAM expansion boards don't work in IIc+'s!

: Applied Engineering made a RAM expansion board it called "Z-RAM"
: (3 different versions) which plugged into the 40-pin 65C02 socket.
: The 65C02 plugged into the A.E. board, and it was a pain to plug
: the RAM board into the 40-pin 65C02 sockey on the IIc+ motherboard.
: There was also a jumper to a pin of another chip on the motherboard.
: (A Z80 chip on the reverse side of the RAM board provided dynamic
: refresh to the D-RAM chips.) They worked on all IIc and IIc+
: models, with or without the memory expansion socket.

: Z-RAM can ocasionally be found for sale on eBay. It's expensive
: there though. It should come with AppleWorks expander software,
: which has patches for AppleWorks to recognize the extra RAM. All
: software must be modified to recognize extra RAM with special
: patches. I remember my disapointment when I plugged my first
: RamWorks board into a IIe and AppleWorks didn't recognize it...

: Good luck!
