Hope someone might help with this question. After months of scanning TAS for a reasonably priced 128K RAM card for a 48SX/GX, I finally gave up and decided to make my own. Using plans from hpcalc.org and updating the BOM to a Cypress memory device, I managed to assemble a half dozen cards.

What did you use for the actual board? Is the edge connector a standard size?

(Sorry if this is a dumb question but it's not my area of expertise and I don't even know what to Google for.)
