Marty - I have not spent enough time on system 80 MPUs to assist here, so I'm a little "out of my depth" - But - If you need ROMs and you want to "dig deeper" with the board - Try Ed at GPE ;

I'm thinking of getting a Quickscan - Just for a "play", as I have quite a few Sys80 boards I need to fix. Clay gets dirty in his guide;

I might have an untested board you can use for testing.

Thanks Nino,

I've sent Ed an email for a couple more spare parts.  He is a System 80 guru.  He is out of stock of the Quickscan's, but I'll wait for his response to see what he recommends.  I am thinking it would be a good purchase either way. (hmm, maybe a HH too one day!)..
