While that's to some extent true, I don't consider it cheaper to replace a RamWorks III + 8Mhz ZipChip :-) I've tried for years to find a replacement Zip Chip without luck. That's the nice thing - we could recreate a lot of the really hard to find hardware very easily. The real expense is in the production of the circuit board, IMHO, and whoever develops the thing is going to require a development kit, although once the board is complete, it would serve as it's own development environment
There is a 4MHz Zip Chip on eBay right now.
