In the days when SCSI II was the fastest interface ( late 80s ) IPI was 
developed to be even faster. It started out at 20 Mbs and was planned to go 
to 80 Mbs. The BIIN Computers used SCSI for most of the peripherals but used 
mirrored IPI drives for data storage. The drives were manufactured by NEC 
with 9" HDAs IIRC. 1.2 Gig was a small drive. I am not sure what happened to 
the technology.

I have two or three 4/690MP IPI controllers that I would consider parting 
with. You can daisy chain the drives but I am not sure how many can be hooked 
up at once. Somewhere I have some IPI terminators also.
