Micro Professor. By Lee Davison.
Introduction.

I managed to get this Z80 based single board computer in a swap for an Acorn Electron system. I'd wanted one when they came out but, as a lowly student on a grant, I couldn't at the time afford one.

Here are the circuit diagrams, a large jpeg picture of the Micro Professor itself and dumps of the ROM from the trainer MPF1 I have. These are for the original Multitech board and not the version Flite Electronics still sell.

I hope in the future to add diagrams of all the add on boards and details of other projects for this computer.

    Of the two MPF-1s I have one was used as a Z80 trainer and has just the one ROM. I don't have the manual for this machine so know little of what the code examples that seem to fill the top half of the ROM do. I also don't have the source for it. The other ROM image is the expansion ROM that was in U7 of my MPF-1B.
