I'm looking for the old-style mechanical switch plate for the Videx 80-column card. Yes I know the new auto softswitch board is "better", and I actually have one of those. But I'm trying to build a machine with authentic earliest-model parts, and for the Videx card the earliest model was a mechanical switch. I you have one of these that you're willing to sell, then let's make a deal. Thanks!
The plate on the righthand side of the photo below is what I'm looking to buy:
If you want even older you should get an M&R Sup'R'Term which predates the Videx card.
