    Thanks Mike, but please, read again:

I've read it again, and I'd still say that although it's somewhat relevant
it's not what Tony was talking about.

Although the pictures and schematic illustrate the general idea of (badly)
making this *kind of* adapter (try reprogramming that EPROM ;-), I think it
would have been more useful to link to an illustration and schematic of what
Tony was actually talking about, i.e. adapting a 2716 (instead of a 2364).

You can buy those adapters for $5.00, by the way.

Am I missing something?
