Add 32kB BANK 2 to your NEC PC-8201 or PC-8201A
NEC originally shipped the PC-8201 / 8201A with only 16kB in Bank 1, but it can support 2 banks of 32kB. These machines use the same SRAM modules as the Model 100, so to upgrade it fully you would need to buy 6 of these modules! Ouch!
This add-on card plugs into the SRAM sockets associated with Bank 2 - slots 5,6,7 and 8 - and provides a full 32kB in one go!
There are two socket styles I have encountered - round pins (most common) or flat pins (less common). These are shown below.
The placement of the 32kB BANK 2 SRAM card is indicated by the red box. Also shown here - REX# for NEC is installed in the Option ROM socket, and 8kB SRAM modules are installed in the 3rd and 4th sockets of Bank 1.
