I have to check but I think there is a "regular" 3.5 to PS/2 drive adapter around, someone selling one? IIRC the PS/2's need a power line (or two) merged into pin X (?). It may be worth it to investigate the possibility of buying or making an adapter as these PS/2 drives are becoming hard to find.
I might not be remembering correctly (un-refreshed wetware), but I thought that I remembered from 30+ years ago, that PS/2 drive connector consisted of 40? pins, of which the first 34 were standard? drive pinout, plus the added pins carried the power.
If that remembraance is close to correct, then the adapter would consist of 40 pin connector to 34 plus power.
