The 8iSwitches board is a replacement for the switches board of the PDP-8/i front panel. This board isn't usually a problem, but it happened that this board in my spare panel was trashed.
Connections are provided for the traditional surface mount ribbon cable attachment, or the installation of headers and IDC connectors for the ribbon cables. Mechanically and electrically, these are drop-in replacements for your existing 8/i switch boards.
Since switches that fit this board are virtually impossible to find, it isn't clear that there will be demand for these. I do have 3 extra boards, though, because I had to order the minimum quantity.
The boards are double-sided, with plated through holes, solder mask on both sides, and silk-screen on the switch side.
Note that to build this you also need the unobtainium switches (good luck!) as well as the 1/4" PCB-mount spade lugs. Contact me if you need help locating the latter.
