I had a spare PowerBook version of a BlueSCSI v2 and wanted to make use of it, so I designed a PCB to adapt the 40-pin connector of the PowerBook to the standard 50-pin connector. I then designed a mount for installing it in a computer. The BlueSCSI is intended to be soldered on top of the board with the 40-pin header between. The power connector may be extranneous since the BlueSCSI should be able to take termination power.

40-pin header: Digikey part number 62004021121

50-pin header: Digikey part number SBH11-PBPC-D25-ST-BK

Any 4-pin header should work for power for use with a floppy drive berg connector.

The board was designed with KiCad 8.
