Probably worth merging the thing into the app note.

Might have a go later.

Hi Paul, Is that JPG ok? I can scan at 600dpi - if you want Tiff or PNG just let me know (21MB/27MB).

Re: Mystery System? Backplane Circuit Diagram

I think I found what it is.

There's reference to it (107.000) in the 1MHz Bus Application Note but the diagram is missing.

I believe it could be System 2/3 (my system 4 bac...
