One thing comes to mind. We were thinking about creating a Mill 6809
card as one demo configuration that is simple enough to serve as an
example. Unfortunately the schematics we found is inaccurate or
incomplete. Would be great to be able to borrow an operational card to
use as a prototype. Non-destructively :)

Since I started the whole Stellation Mill-on-FPGA thing, I'd be glad
to do the work of correcting the schematic if lent a card.

Alex, I'm glad you said something as I was planning on attempting the
implementation either in FPGA or wirewrapped actual, based on that
schematic I sent you.

The problem with the available schematics is that it doesn't show what
signal controls the address buffers U12-U14. Clearly the card can't
always drive the bus. This may well not be the only error.
A high-res picture of the back of the card may help a lot.
