These boards are for 5V parts which you can still get but are becoming less common. You could populate them but they are not set up for FLASH parts so I doubt that you could convert them to FLASH boards without a fair bit of effort. Also they only have 2Mbit FLASH for presets which I'm guesssing would not accomodate the full preset of later ROMs...

I have seen these boards on ebay before. Other people with more expertise than me will have to determine whether or not these can be populated with chips that are currently available or if new boards need to be designed. That is way beyond my area of expertise.

SO if I can sell 50 I would probably break even at around $100 each... but If I only sell 25 I get stuck with $2500 worth of stuff that I can't do anything with. If I can sell 100 I might be able to do it for $65 each. So I sell them at a price to cover costs. And I still don't get compensated for time and effort.
