Jim,
Some of the AS/400 manuals show how to connect the drive. The small
connector with the trailing bus and tag leads goes in the AS/400 and the
bus and tag go to the drive. The manuals also suggest there should be a
grey and a blue bus/tag cable.

I think on the AS/400 there is only a single cable at
least for the 3410,
and not bus / tag. If this was hooked to a mainframe with bus / tag, you
won't get it hooked to an AS/400 with the same electronics.
Also you have a mix of 370 and 390 cables, there are frequently issues
with which you use where. I think you had to have 370 cables between the
controller and the device, but the blue cables would work for the channels.
I'm interested in that you do have what looks to be bus / tag termination.
However photo of the connector in the device has only one connector
visible with power cabling blocking the view of the bottom of the channel
connector. If there are bus / tag connectors below then I'm a bit confused
about what you have given that the ones we had only had one cable.
I bought a lot of equipment at one time and snagged one off of an AS/400
before I found out it didn't do mainframe, and at least for the 3410 is a
single cable affair.
the 3430 we had at a facility I worked at was a single unit and had to be
an A unit, but I never looked into the box to know what it looked like.

According to:-
http://ed-thelen.org/comp-**hist/IBM-ProdAnn/3430.pdf<http://ed-thelen.o…
only the "A" drive has power, the "B" is powered from the
"A" so it looks
very likely that you have an "A" unit.

I suspect it is an "A" drive as it has a pair of BUS and TAG sockets and
normally on Mainframe channels only the
"A" type devices have these, and
then the "B" drives use some other kind of cable to tie into the head of
string but this may not be true for 3430 drives.
However there should also be some jumpers to set the channel address and
I
can't see those any where, so perhaps 3430 are daisy changed alog the
channel...

A good friend has a well preserved IBM 3430 tape drive, originally
connected to an IMPI AS/400, and we are now
hopeful that it could be
reconnected to a slightly more modern AS/400, still IMPI and still
SPD. This would give us a local 9-track tape capability:
here are some pictures:

What we are particularly interested to learn is whether we have the
"master" tape drive, known as a A01 unit (that includes the controller
electronics) or the tape-drive-only unit known as the B01 variant.
We added a picture today (see very last picture) of the main
controller electronics cage that shows several plug-in cards, is
anyone familiar with these and can identify the variant by sight? we
searched the entire machine looking for some designation that showed
the model variant without success. So we assume it comes down to the
controller cage, and we see empty slots so we wonder if it is the B01
variant.
