RAM Cards & Chips

RAM Card Types

There are 4 types of RAM cards for the Apple II line of computers.

Apple IIgs Apple //e Apple //c

Cards for the Apple IIgs will ONLY work in a IIgs Memory Expansion Slot Cards for the Apple //e will ONLY work in a //e Auxiliary Expansion Slot Cards for the Apple //c will ONLY work in a //c, either plugged to the motherboard or the RAM Expansion connector depending on card/computer type. The RAM cards that piggyback onto the MMU and IOU chips will work on either //c but the cards that have the memory expansion connector only work with that connector.

Apple ][+

Cards for the Apple ][+ will work in a //e or IIgs as well, are usually known as 'slinky' (slot 1-7) RAM Cards and will not function the same as RAM cards for the RAM expansion connectors, meaning they will not be seen by the system as available RAM. Only on an individual software level will they be seen.

RAM Cards for the Apple use CAS before RAS chips. Generally this is not a problem. These cards can use either DRAM chips or SIMMs. However, if a chip type is not listed here. Please find on that is or check with someone for the possibility of another chip type being compatible. (In which case it should get added to the list below)
