The HPDrive page states that the 9914 cannot implement the Amigo Identify
command, as it uses a non-standard sequence (Untalk followed by a secondary
addressed to the device). Yet, I don't understand this claim, as my HP
9134A disc drive uses a 9914A as its HP-IB controller, and it certainly
Are you sure? I don't have a 9134A, but I've worked on (and have
schemaitcs) for the 9133 V/XV and 9133H. The 9133 is, of course, a 9134
with a floppy drive (and maybe a seprate controller card) added. As far
as I can rememebr, all those units use the Intel 8291 GPIB chip.
Can you please check the 9134A uses a 9914. I am very suprised.
