Yes, a very nice design. Kinda tough to get ahold of

Um.. you do realize I'm one of the two people who sells the P112 kits.
We tried to take orders for a production run, but didn't have enough takers this time
around to fund a run. We do have a small number of kits available, however at the moment
I don't know how many of them are spoken for. Contact Dave Griffith (he's on this
list, or at his website at
frotz.homeunix.org/p112) if you're interested. Also, as I
stated a couple of months back, there are blank boards and a very limited number of the
surface-mount components available direct from me (
http://p112.feedle.net/).
I haven't been able to follow this thread quite like I would have hoped: but, it's
worth noting that if people are interested in a basic CP/M design the P112 is about as
basic as one can get, and is about as "open" of a design as one can get. The
challenge that we have right now is that the FDC chip is an obsolete part, and I don't
think there's a drop-in replacement.
It might be easier to see if the existing P112 design can be worked into a different
controller, or if a custom (preferably 'open source' licensed) new part can be
engineered. It's a bit out of my expertise, but I think I can safely speak for Dave
and say that any work towards a drop-in replacement with minimal re-engineering of either
the board or the ZSystem software would probably be warmly welcomed...
