Vintage EPROM ROM Board w/ AM1816-2 & MHEC Gold Chip Arcade Dev Retro PCB

Untested vintage ROM/EPROM module pulled from surplus decades ago—likely late '80s to mid-'90s vintage. Features an AM1816-2 controller IC (Singapore-made) and a gold-label EPROM from MHEC. The board appears clean with no obvious damage or corrosion. Pin edge is intact, and solder joints look solid. Possibly from an arcade machine, dev kit, or embedded industrial system. These vintage RAM sticks are untested. I don’t have compatible hardware to verify functionality, but they appear to be in excellent physical condition. No bent pins, corrosion, or visible damage.
