Price List and Stock levels
Prices are listed in USD, but since I live in Canada, I request payment in Canadian $. I convert from USD to CDN using the current exchange rate, and then add postage in CDN.
Note: pricing has been adjusted to reflect supply costs.

PC-8201 BANK2 32kB/16kB SRAM card
PC-8201 BANK2 32kB SRAM card information
Have a PC-8201A with only one Bank? If you open up the memory compartment, and RAM 4,5,6,7 are empty then this is for you. This single card provides 32kB for Bank 2, replacing 4 "standard" M100 8kB RAM modules. It plugs right in!
If you just want to add 16k to Bank 1, I have a derivative product for that as well.
Note: Most 8201A have round machine-pin receptacles, but some have IC sockets that take flat pins. At time of order, confirm the type of pins you need.
