Selling D&N 64K CMEM Expansion Board

Post by lowrybt1 » Tue Jul 02, 2019 6:20 pm

I have a D&N Micro Products 1564 (CMEM-64 Expansion Board) pulled from a C3-OEM. The board has 64K of 6116L RAM, appears to have two serial I/O ports populated, and also appears to have most of the IC's and other circuitry for interfacing with 8" floppy drives. I installed the board in my C8PDF. On reset, the system returns 0000 11 (or 0000 77, I can't tell which because the LCD TV clips the top row of pixels). I don't know what that means and I have no documentation though I have hunted high and low for it. Anyone interested in it, PM your offer. Thanks, Tom
