Bill Sudbrink said: I'm in no hurry. Thanks for the offer, but you just finished supplying me with all that documentation on the C4P. Someone just down the street from me says he has documentation and schematics for the mother board. I'll check that out first. He also pointed me to a couple of great Compukit 101 pages: http://www.compukit.org/ http://www.home-micros.freeserve.co.uk/uk101/uk101.html Looking closer, there are sockets on the mother board for 8 pairs of 2114s. There is one pair of 2114s in the first pair of sockets and one pair of 2114s in the last pair of sockets. It looks like the select lines for the 6 pairs of sockets inbetween are wired to these 2716s. So it has the feel of some kind if firmware application.

I'm sure she just wants to make sure she doesn't stumble into the kitchen one morning and stick a Pop-Tart into one of your drives. In your house there is a path through the garage, a path through the living room, a path through the dining room, and one bedroom that I can just look into. My wife just wants a corner in the dining room to set-up a trendmill. --Doug ==================================================== Doug Coward dcoward(a)pressstart.com (work) Sr. Software Eng. mranalog(a)home.com (home) Press Start Inc. http://www.pressstart.com Sunnyvale,CA Curator Analog Computer Museum and History Center http://www.best.com/~dcoward/analog ====================================================
