I am in need of a MK4 roll scanning board. These are the electronic
boards that were designed for Larry Doe's brilliantly designed MK4
bi-color roll scanner.

Around 2004-05, when the scanners were being constructed, a quantity
of these circuit boards was made available.  If you have one of these
boards that you are not using and are willing to sell it please contact
me.
