Yeah, I know how hard it can be to get pictures of boards, enclosures, etc.
I suggested scanning because I heard that's how the folks who put together
the Q-bus Visual Field Guide did it and I feel they had pretty good

Given optimal conditions you can get nice results with a good camera. I had
a friend of mine shoot my ROLM CBX boards with a Canon 5D at maybe 30-40
degrees off vertical with them sitting on a piece of plywood under direct
sunlight (outside in the middle of summer) and I was very pleased with how
it turned out

(see: http://wildflower.diablonet.net/~scaron/rolmfieldguide/index.html)

I never really had good luck with the camera indoors under artificial
lighting though, although I don't have much in the way of professional
lighting gear... I was always trying to just shoot under standard
fluorescent shop lights... I find it hard to get that balance in contrast,
where no part of the board is too dark, without annoying glint, shine or
reflections on other bits of the board.

The one I have is a 66503 Rev B board with 8x TMS44C256 DIP RAMs... As I
say, I'm only good for 600 DPI or so but I'm happy to scan the one I've
got. If you were local I'd just give it to you.
