Hello All,
Recently I came across a complete Pertec interface (card, manual, software,
and, cables) thanks to list-member Shaun. Of course what is the point of
having an interface if you have nothing to interface it to!
So I've been looking at, and learning a bit, about 1/2" tape drives. I've

I'm confused on some of the terminology. I don't think that I'm alone.
A friend of mine was in law school before he'd believe me that
"burglary" and "robbery" were not fully synonymous.

Arguably -- and I'm aware it's stretching a point -- it did, in the
form of DR-DOS.

Ali,
I recently bought a Qualstar 1052 from Nico de Jong, which may fit the bill
if you're happy with 1600 and 3200bpi. I believe he has another available.

Well, the Altos ACS-8000-2 power supply is all back together and working
again, in reasonable health. And, as I posted a few days back, I
swapped out the bearings. Unfortunately, that does not seem to have helped.

There is one jumper that controls DD/HD switching mode.

I should have been more clear - the manuals were for the ISA interface card

Glen,
Thanks for the recommendation. I had actually seen the drives you linked to
At microdata we had a support contract with Data I/O and every set of
roms for the base unit and the Unipak came with a new poster up to date
with the latest parts from the manufacturers.
So you don't need to just get a poster or table or list, but you also
need to match it to the firmware set
