I have a number of non-functional older PalmOS devices (of the 68000 processor variety, not the later ARM processor models). I'd like to be able to reuse the memory cards from these in new applications, but I'm struggling to find much information about the cards. What I can see is this:
The cards use a form factor similar to a modern SO-DIMM; the clip mechanism is essentially identical to a modern laptop's memory cards.
The interface has a 72-pin double sided connector.
Some of the devices I have have a seperate ribbon connector to the main board, although this may be a proprietory extension as these cards came from enhanced PalmV devices with barcode scanners manufactured by Symbol.
I would ideally like to know:
What precise connector model is used to hold these cards?
What RAM technology is used? (I'd usually assume traditional DRAM, but there's a possibility that SRAM was used to increase battery life)
What is the pinout of the connector?
What is the purpose of the extra ribbon cable connector on the Symbol devices?
