(deleted stuff about the expensive products available)

Well, that sounds like an easy solution, though an expensive one.
Perhaps it's the documentation that costs so much.  The prom and
multiplexer chips don't cost near $60, and the rams shouldn't cost
$70 either.

Disclaimer - I do stuff like this to make money, but I don't think
that 1000% markup on a prom (or just 100% on rams) is good for the
business.
