It's a 4.2-R system. Here's the relevant part of the verbose boot (without the new DDYS-T18350N because this makes the system hard to use). The 68pin cable is about 60cm with 4 connectors every 20cm. The active terminator was way expensive (DM50 = US$25). The 50pin cable is 150cm long, with 8 connectors spaced 1--------2-3-4-5-6-7-8, aic7880 being at position 1, the terminated IBM DCAS at position 8 and other unterminated SCSI2 devices at 5 and 7. I'll try different cables as soon as I can get hold of one. Thanks for your aid in tracking this down.
