If you don't wantto etch your own PCB, it's relatively hard to get a male card edge conenctor (and if you do etch your own board, it's non-trivial to gold plate it). it is, however, quite easy to get header plugs of various sizes, including ones with wire-wrap pins. If I ahd to make such an adapter in a hurry (== no time to make the PCB)_, I'd probably put 34 pin and 50 pin wire-wrap headers ont a bit of square pad board, wire-wrap approrpraity, and fit one of said adapterso nto the 34 pin header to conenct to the edge connector on the cable. FWIW, I sued such adpaters to make Vektrex cartirdges some years bakc The Vectrex cartrdgi9e conenctor has 36 pins IIRC, but you don't need the rearmost 2. So some od said adapters with a wire-wrap IC socket -- one row of pins bent out at 90 degress to plug into the adapter, the other soldered to a bit of stripboard with pins soldered to it to go in the other row of adapter holes -- was essentially all that was needed. -tony
