When you boot the 64000 off the first two diskettes in
the operating system set, it checks the HP-IB for any
devices attached. If there are no devices attached,
you get instructions displayed that state that AMIGO
devices - and it names the 9134A - need to be set as
address 0. With the drive attached at 0 , it reports
the 64000 itself, and an unrecognized device at
address 0.

I have a untried 9000/300 unit that I picked up last
year. Perhaps I could try using that to test with.
Will a 9000/300 try to boot without a keyboard
attached ? Of course it would hard to press a key to
stop the boot sequence without having a keyboard
attached <g>.

It's the big beige unit. There's no fault light on it,
just the power light and the disk activity light.

Just to see what would happen, I hooked it up to an
HP-1631 and went through the Storage menu to see what
it detected on the bus. I can see the activity light
coming on when the 1631 tries to access the unit.

The Zia Tech unit is less of a card and more of a
programmer's panel sort of device. It has a couple of
rows of switches and lights that correspond to the
data lines and some of the HP-IB commands. It doesn't
seem to have any address setting capability on the
outside of the box. Maybe there's a DIP switch inside
or something. Looks fun though.
