Well I have my 9134A connected to an HP-87 and when the system boots
it recognizes the hard disk automatically, so that you can just type
a CAT commend and see the directory listing.
One question, I assume that you have set the two address switches
on the back to *different* addresses (e.g. HP-IB addr 0 for the hard
disk and addr 1 for the floppy). So if you try to do a CAT on the
floppy address, do you still get a timeout?
