Do you have an Arrick Quick Switch printer switch box with card edge connectors?

[Ragnarock]

Would anyone happen to have an old Arrick Quick Switch from the early 80s in their junk bin? They had card edge connectors for the TRS80 I and III. We made a few thousand. Several hundred were hand nibbled and hand-lettered by me early on. Lots were sold here in the DFW area through computer stores. The boxes were metal silver and black.
