Hi Leonard

Well, interesting you should say that...

http://fpmini.pbworks.com/w/page/39529866/FP%20Mini

We've already designed such a critter. However it seems to have run into significant technical problems.

I'll let Don Caprio, Rich Cini, and John Monahan get into the technical specifics but as I recall it would require major redesign to be a "general purpose" S-100 front panel.

Maybe it could be done? There were at least a couple rounds of prototype boards built. It seems a shame to let it gather dust now though after all the sunk cost and effort that went in to it. Blood, sweat, and tears (mostly tears at the end...)

I still support the project but it may require some super-human effort to fix it. Not a challenge for the meek...

Thanks and have a nice day!

Andrew

This may not quite be the right thread, but...

How about some sort of front panel or ability to perform the Imsai/ Altair front panel functionality (ss, set address, run, stop, etc)?

Either on board the CPU or daughter board, or even a semi look-alike front panel? Just a thought. Front panels are cool and useful at times!

Thanks for all your hard work, as well as the great efforts of others.
