Hi,
I’ve been trying to find *detailed* specifications (mainly detailed signal
timings) for the SMD disk interface but all I’ve found so far are the interface
specifications for individual disks (CDC, Fujitsu, etc). I’ve looked in the
usual places (bitsavers mostly) and haven’t found the spec
ANSI has a spec, X3.91M_1987 I don't know if it covers the SMD-E , etc.

Hello,
Can anyone please point me towards a copy of the Tapestar utility package
for DOS? I have already contacted Qualstar and they cannot help. TIA!

I'm in contact with the owner, arranging to pick it up. If anyone on
the list is interested, let me know.
This is a "must go asap" issue for the system involved. I'm not going to
ask anything if anyone needs the system, just let me know. I've got a
warehouse in KC near this location where we'
A saint's work is never done! I wouldn't know what to do with it but glad
it's not being scrapped.

Man, that its one nice system. If I didn’t already have a S/36, I would be
driving down there as we speak. Maybe one of these days I will get my hands
on a 9 track for the S/36 like the one in the images.
Oh well, good luck to whoever ends up getting the system!

X3.91M-1987 section 6 covers "Interface Extensions", which includes adding
tag 4, 5, and 6, dual-port provisions, spinup sequencing, index mark and
sector mark

anyone know what system these floppies are for?

Those would have fit a Terak system for UCSD Pascal. I’ve still got a few
stuffed in a closet.

Oh the things companies did to try and increase their profits! Bad idea
indeed, reversible just meant half the profit for the suppliers!
On the same vein, we ordered a TWX line form Bell but supplied our own
machine. Bell said they were not responsible if the line caused errors,
and sent a man
Believe it or not, the "flippy" was actually patented in 1974.

...and let's not forget the 3" CF2 diskettes--designed to be flippies
right fron the get-go.
BASF certainly marketed 5.25" flippies:

Hi All,
Probably a long-shot, but I'm looking for a DECtape drive for my PDP-8/e.
Either to buy or to trade with something. (PDP-8/11 parts, 11/34, Intel
MDS, ASR-33?)
I'm in South-West England but also have an address near LA. Can travel to
pick-up.
Regards,
