So it might be as some suggested, that the DDS drives aren't too happy.
I tried with a DDS2 tape in it, if that matters. The system sees the
drive, and I can mount and dismount tapes, and even eject them. Reading or

I have not verified the drive on any other system either, so there are
several possible problems here, but I thought I'd report what I can

I ended up going with the TZ30 in the /73 due to some difficulties with my RSX-11M+ system
disk not liking the /23+ (I used M+ to write the tape). I'm happy to report that so
far RSTS/E seems to be much happier with the TZ30 drive and a TK50 than it was with a
TLZ06-AA drive and a DDS1 tape.
Yes, I was able to read the tape!

I might be interested, depending on postage costs. Has anyone
in the UK got
an Atari 820? I'd prefer one with a dead controller and a working mechanism
and printhead if anyone on the list has got an 820 (or similar printer) like
that.
At some point, I plan to rig up some form of printing terminal - anyone got a
spare impact printer mechanism (and a datasheet for it)? :)
Thanks.

I've owned both of those printers back in the day. The print mechanism

The 820's simple have a connector row from its custom SIO interface to the
mech, so if you needed a new mech, you'd just pull it out and use it as is,
no mods.... Smart move on Atari's part back in 1980 as they needed
peripherals and why reinvent the wheel when all they had to do was make
their custom interface and us an off the shelf printer mech. As for the
825, its a all Centronic 737 inside, all Atari did was give it a new set of
Atari clothes :-)

That's pretty common, of course. Most IBM PC printers were just Epson's
rebadged. That practice still goes on today as well. Apple StyleWriters
are either Canon bubblejets or Epson or HP.

Thanks but I interested the insides of the SWTPC printer. I'm thinking
the Atari printer mechanism might be put to a lot better use :-)

I don't understand the question. What is it you want to know about the
electronics? The PR-40 was sold as a kit so it would be very easy to work
on. I don't have a schematic, but I think it was mostly TTL with a
character generator ROM. The Atari 820 had more LSI chips, as usual with
Atari, and tin boxes around everything for TV interference protection.

Sorry to jump in in the middle, but my brane finally dropped into
gear and I remembered that I have the Owner's Manual (EK-TLZ06-OM) for
the drive.
It's a DDS1 drive. 90M tapes, 2.0GB uncompressed. The first page of
the overview states that it will work with TLZ04 (60M) tapes, as long
as the data on the TLZ04 is not compressed.
So it might be as some suggested, that the DDS drives
aren't too happy.
I tried with a DDS2 tape in it, if that matters. The system sees the
drive, and I can mount and dismount tapes, and even eject them.
Reading or
writing gives errors, though.
Most DDS1 drives won't even *load* a 120M DDS2 tape. The TLZ06
almost certainly won't read or write to a 120M tape.
The manual doesn't even acknowledge the existence of DDS2 or any tape
larger than 90M, probably because they didn't exist when it was
printed. :)
I have not verified the drive on any other system
either, so there are
several possible problems here, but I thought I'd report what I can
anyhow.
First, I'd try a DDS1 tape.
Also, 4mm drives, by nature of the tape path, are notoriously filthy
around the heads. The tape makes almost a 360 degree turn around a
~1/4-inch capstan, spewing bits of magnetic coating everywhere. A
couple of passes with a cleaning tape often works wonders.
I could scan this manual if need be. I don't have any OCR software
at present, but I could come up with a creditable imaged pdf.
