Does anyone know were I can obtain a diode matrix blank printed circuit board. I have used Traintronics SwitchMap in the past, but they seem to be out of business.
Never even saw that one, but they aren’t too hard to build yourself on plain perf board. Easy way is to use bare copper wire and run the rows on the top and columns on the bottom so there is no chance of shorting, a lot easier than trying to have both wires on the same side of the board and needing to put insulation where rows and columns cross.

Lots of info for DIY if you search it out.
