RE: Floppy drives on ancient AS/400's

Yes, and you could create a diskette writer.

"Those diskette drives even had, for some forgotten reason, an output queue assigned to them."

I never knew that.

The IBM System/38 used the same bus and tag cables to connect to the
I/O devices it used ... many were the same DASD and tape drives used by e.g.
the 43xx line of mainframe products at that time.
The AS/400s with the SPD bus had an optional IOP/IOA that would allow
you to attach any mainframe style "bus and tag" I/O devices, usually large
(vaccuum column) tape drives ... I recall one customer had a nice big
Memorex tape drive attached to their AS/400s in this manner.

Once upon a time we had a 2440 tape drive. It was mounted in the rack
and stuck out the front if I recall. I've googled, but not found a
picture yet.

I think ours was 4U and you could slide it out when it was working.
It had a clear top and after you slid the reel in it was fun to
watch it try to autoload the free floating end on to the take up reel.

IBM did have this huge 3phase vertical tape drive for the AS/400.
We
even
rewired the computer room to 3 phase to get ready for it but we
never got it. Was that the 3490?

I believe there was one vertical column tape drive supported on the
earliest machines. Most though were rack mounted about 5U or
available as table top with a cover.

The most common early unit was 1600 and 3200 BPI (the later not a
standard density) It had a smoked color plastic door that you
really couldn't see through. The control panel was terrible and it
was so unreliable it was referred to as the '9347 piece of shit.'
IBM replaced the planar board in ours half a dozen times. It was not
an IBM manufactured drive. The 9348 replace it and it did 1600 and 6250 BPI.
(It could not read the 3200 BPI tapes) It was fabulously more
reliable and the same size as the older unit. Tapes in these were
slid into the front like a pizza.

Hmm. As it happens, the 4341 I mentioned in another thread had 8"
floppy
drives buried inside at least one, and possibly several, of the
cabinets.

BTW, are there any pictures of what a 1/2" reel tape drive even
*looks
like* on an AS/400? Does it look like your typical mainframe tape
drive,
vacuum columns and all? (I think the only place I can recall
seeing
tape
drives of that sort in operation, in person, is at the Computer
History Museum, in Mountain View, on their restored IBM 1401 [and
maybe also their restored PDP-1, although I think *that* uses a
*punched paper
tape* drive]).
