FWIW
Several times there have been discussions on this list about wheather or
not IBM ever made cassette drives for use with the original IBM PCs. The
general feeling is that they never made any cassette drives or tapes. BUT I
was talking to Mike Haas about this recently and he told me that he has an
original IBM Diagnstics cassette tape! Today he sent a picture and I've
posted it here <http://www.classiccmp.org/hp/ibm/ibm-cass.jpg> . As you
can see it has the same burgundy color as the standard IBM PC diagnostics
disks.

Yes, I have several of those tapes. The most reliable information I have
on this comes from Fred and Tony, and that is that the IBM PC used the
same pin out on its cassette port as the TRS-80, so you could go to Radio
Shack, buy the TRS-80 cassette cable, and use whatever cassette player you
wanted.
Although I have never seen an IBM branded cassette player and doubt that
there ever was one, I will NOT say that it probably never existed because
as soon as you do, someone turns one up and proves you wrong ;)

Hmmmm. I'll hereby state that a working boot disk for a Diskon DOES NOT
EXIST! (It's a dedicated CP/M based disk format conversion machine with
external drives and CPU built into a Televideo terminal housing)
... and nobody in the world knows the meaning of the bits where the
attribute should have been in the Panasonic word processor format.
... and nobody has written a graphic equalizer for the Ipaq.
... and nobody knows what bar Shugart was at when the 5.25" disk size was
decided.

When school got it's first IBM PC, it came with a cassette tape , it was
purchased direct from IBM (supposedly) and the tape was a Panasonic with a
sticker on the bottom that stated for service of the tape unit we should
contact the local IBM field office. it wasn't IBM branded... the cassette
cable cost more than the tape player at the time ~$75 for the player, and
~$150.00 for the cable

Yes, they provided diagnostics on tape.
Yes, there was a cassette port.
Yes, the pinout was the same as TRS-80.
NO, we have NOT seen an IBM cassette drive.
No, we have NOT seen an IBM cassette cable.

I installed an entire classroom of IBM PC's that all had cassette interfaces
on them, but never have I ever seen an rebranded or OEM's tape drive
directly from IBM themselves. The Diagnostic tape, was it to run diags on
the IBM PC itself or was it a diagnostic tape for a tape drive??? I have
several diag tapes for the Atari 410 which test the alignment and speed of
the Atari 410 tape drives, so this is why I ask.

It is diagnostics for the PC.
Almost, or maybe exactly, the same as the diagnostics on disk.
I have never seem the "Advanced Diagnostics" on tape, but have been told
that it existed.
Perhaps the reason that nobody is familiar with the IBM cassette drive
might be because there never was one?
But the PC DID come with a diagnostics tape. It was simply assumed that
the tape drive would be user provided. That way IBM was off the hook when
it didn't work.

I can vaguely remember that we had PC's outfitted with cassette units
when I was in the first grade. The machines were used to teach
reading. They were part of course material published, at least in part,
by IBM that consisted of software for the PCs and workbooks.
From what I can remember, the software phonetically
pronounced the names
of objects on the screen. I don't recall if the cassettes
actually
contained software, or if they were used to produce the spoken voices.
Needless to say, this system taught me to read.

Many of use have. The original PCs all had the cassette port.

AFIK no one has. That's why I was surprised to hear of someone having a
tape for it.
The Diagnostic tape, was it to run diags on

No, this one has diagnostics for the computer.
