Are you sure?
Original mainboards don't have a 50 way connector where as Alpha Plus (Premium Series) and 256TC mainboards do.
A DRAM microbee with original mainboard (e.g. CIAB, 128k, starnet workstation/server) could have a 50 way connector added using a horrible adapter PCB that fitted under the mainboard.
