BTW, the FFF EPROM is currently available on eBay.

Unfortunately it's an older version and the seller is known for unfair prices.

Yeah, saw that. Reminds me of the old joke about the kid selling a cup of lemonade for $50 (only need to sell one). I've looked at the labels of the two ABACUS ROMs and I'm beginning to wonder if my own might have come from ABACUS itself. Label was peeled down to show the CMT logo.
