Is the SCA SCSI output for U160 or U320?

If the former, I think you should be OK. It'll be interesting to see if your IDE->UltraSCSI adapter does a better job of it than the ACARD IDE->SCSI ASIC.

If the latter, it may or may not be backward compatible with the original (Mac) SCSI spec.

Good luck, I'm following this I/O hack with great interest! :approve:

edit: That'd be way cool hooked up to your fast/wide JackHammer SCSI II Card, BTW! }
