Below is a clip from a usenet thread. 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.

I've never taken them apart to check it out, but how different are the RAM cards between the IIc and the Laser 128? I've got a couple of 1meg RAM expansion boards for the Laser 128, none of them have any of the RAM chips installed. I also have what appears to be a proto or knockoff of the same board, fully populated. The layout is the same but instead of being on the standard green PCB, it's on a silver metallic one and all the chips are socketed vice just the RAM chips on the factory boards. It also doesn't have any markings on the board at all.

Actually I emailed them to see if I could cut a deal on a Focus drive and memory expansion. (I have a few sealed cases of a part they have been out of stock for a bit on).
