[Coco] 512K upgrade for CoCo 3 on eBay

[Bill Pierce]

Actually, that looks like the upgrade by "Performance Peripherals" from the 80s/90s. They were the only upgrade I know of who's memory board was upside-down (something to do with heat dispersion). They were considered one of the "premium" upgrades at the time. I have 2 and both have served me well and still work.
