WDC Expansion Boards

WDC just put two expansion boards for their SBC's up for sale on Tindie.

The 65C816 expansion board includes 512K parallel SRAM, and so is probably the easiest way for a newb to add memory to the SBC.

Nice find.... WDC is also selling them on their WDC65XX store as well. They also note that several of the chips are not populated due to manufacturing availability. Mouser shows stock of the SSRAM, but none of the others.

From the WDC65XX site, the getting started link has some code to make it go:
