Thanks for the memory!Here are the memory chips for the Apple IIc. The system came with 128K of RAM, but it could only address memory in banks of 64K. You could expand memory to over 1Mb in size, but this memory was also only available in banks, not as a contiguous 1Mb.
Our Apple motherboard has the base memory soldered on. Memory is expanded via a card whose connector is off the screen to the left. First generation Apple IIc motherboards had socketed memory chips which all had to be removed and replaced for upgrades.
