I'd say that probably the IBM disk isn't high-voltage. The 735's 
fast-wide is fast-wide-highvoltage-differential, back then they thought 
that no one in their right minds would try to do FWSE and no one had 
thought about LVD yet, or something...

And IIRC the -wd in the Seagate model code means about that too. I don't 
know about IBM specifically.

Well, if it works in a normal PC, that usually means that it isn't HVD. I 
only know of two HVD adapters for PCs, Adaptec AHA-1744 and 2944, and 
those were always expensive ...

I suppose you could get the disk to work on a single-ended interface or 
get an appropriate EISA card.

Besides, do you mean that the 735 FWD interface works in Linux/parisc 
nowadays? Great...
