Thank you!  Now that someone has confirmed it is possible we
had better look at the hardware again.  You gave us all a big
clue; you have 5 targets on your SCSI bus whereas I have only one.
I guess the extra capacitative loading may dampen down the ringing
which is already known to be a problem with the 1542C.
The F (fast) version may just have the same problem but worse!

I am going to experiment with different cables and terminations.

Cheers ... Martin Allard
