Also, if you could include a bitmap of the rest of the Percom card before the initial enhancement work, that would be useful as well. The bitmap you included helps eliminate some ambiguities that show up as enhancement artifacts, as some of the component numbers go from being barely comprehensible to total head scratchers. Others aren't readable on either--but I've been able to suss out enough that I'm sure I can build a good one from this. One oddity that I will have to compare to my card though--it looks like they weren't using 74LS244s to buffer the address lines per the diagram, but I thought they did on the board. More nice things to look at.
Thanks for scanning the other diagrams as well. My eventual goal is to have nice diagrams for every card out there, but that is a long-term project, as I've only completed about 25 pages of schematics in the last year.
