Hi,

Was there a SCSI interface for the TU81?? 

A Qbus-ISA interface should be fairly straight forward to implement in 
a programmable logic device (XPLA,FPGA). eval boards are cheap enough.

I did something similar to transfer data between a unibus machine & ISA.
But you're on your own for software..

Cheers,
     Steve
