Hello all,
I got an HP7974A 9-track Tape. Is there anyone on this list who has some
documentation about this tape. Esp. I'm interested in servicing
informations, schematics and manuals.
As I already often noticed with other tapedrives it's drive capstan has
turned to goo. Has someone hints or experiences in repairing the rubber
of a tape capstan.

I've got one as well. No schematics or service manuals, just the plain
users manual, okay had to look: "The HP 7974A Magnetic Tape Subsystem
Operator's Manual". It does have the test numbers and error codes
but it's a bit on the thin side.

New subject: IBM drives in a Kaypro
I got this message from a guy today, and I am just wondering if he is
correct, will the IBM drives work in the Kaypro?
5.25" full-height, 360 KB floppy drives
(the big black ones)? Do they work?
I'd be able to use them to restore a pair of old Kaypro computers that use
these drives. The "B" drive on each Kaypro appears to
be shot.

They probably should. I came across a TRS-80 Model 4 with IBM drives that
worked fine.

Yes, they will work fine as will half-high 360k drives but you
need some 'gap fillers' to make it look right.

With a few exceptions (most notably Apple and Commodore) ALMOST
everybody used "SA400 interface" "industry standard" drives.
but you might need to set the termination and jumpers for drive select,
head load, etc.
Yes, the IBM drives will work in a Kaypro, TRS-80, Morrow, Zenith,
Northstar, ...
The different types that you need to be concerned with are single v double
sided, 48TPI v 96TPI (the 100TPI is VERY "rare and valuable"), and amongst
the VERY oldest drives - the original model of the SA400 was only 35
track.
Of the machines listed at http://www.xenosoft.com/fmts.html all but a
few use the same types of drives.

Good grief, I must be rich and didn't realize it with a box of 100 TPI
drives (used on Micropolis systems and Vector Graphic systems IIRC :).

Yep

The original IBM PC (and PC/XT) drives were _standard_ 40 cylinder Tandon
units with 'IBM' moulded into the faceplate. They are electrically and
mechanically the same (I've compared the schematics...). There's even the
standard configuration jumper block on them (which was always set the
same way on a PC -- the same way on both drives -- due to the IBM twist in
the cable).
Provided the Kaypro also uses standard drives, then they should work
