I don't think
the Apple (][) would be able to keep up its 1MHz clocked
bus with the 5MHz-clocked SCSI(-1) bus. Other than that, it should not
be too hard to grab a cheap NCR chip, stash it onto a board with some
ROM and buffers, and type PR#5 :)
If you could buffer the data enough, this should work, because SCSI1
doesnt do sync mode data bursts, hence, the Apple would not get
"bombed" with data all the time, just in spurts. Using heavy
buffering, things would work.
