There was once a website called "The Totally Unofficial ATW800 Page"
that was maintained by Chris Gray. Unforunately, it died like the
dinosaur years ago when the host provider decided accidently to end his
web account. I archived it locally on my website with the Chris'
permission (thank god for the wayback machine). It is basically
verbatim from the original site. You can find it here:
http://www.classiccmp.org/transputer/rtu_atw800.htmhttp://www.classiccmp.org/transputer/gs_atw800.htm
If you go the ATW800 specs, there are a lot of links to other users who
have the ATW800:
http://www.classiccmp.org/transputer/atw800.htm
These guys are more than happy to help fellow ATW800 users (especially
Jean-Marie). Also, there are much more documentation on ATW800 on the
previous link that is not contained in the Helios link...
I wish I could help you further, but I don't have one :-(
Cheers,
Ram

Curt has one. The software is on my website at

Not a chance! Tony Duell can give you all the technical details but the
short version is that drives are completely different. The good news is
that 9122 and compatible drives are frequently cheap on E-bay and in
surplus stores.

I was cleaning out a cabinet to make some room and found several diskettes
for a Dynasty Smart Alec II system. Format is SSDD 5.25 48 tpi, but for
the first track which is SSSD--the system is CP/M-80.
I can find scant information on the web about this beast--I'm curious if
someone can fill me in.
Cheers,
Chuck
Saw a Data General MV/1400 machine at a client site yesterday acting as
a coffee stand!
It's about the size of a 6U rack server standing on its side, mounted on
a 'foot'.
Apart from an ON/OFF button and the name badge, the front has a QIC-type
tape drive, and next to it a blanking plate that appears to be able to
house either another QIC drive or a floppy drive. Nothing else
interesting. Unfortunately I wasn't able to peek at the back.
Google didn't yield much on this machine. Anybody know more details?
Glen.
Anyone still looking for one of these? I found one--I had it stashed away
with a bunch of PC CMOS clock chips.
Drop me a private email if so.
Cheers,
Chuck
on ebay. search it and check it out.

Hi
I've used a sharp chisel and hammer. No matter
how you do it, you'll break some plastic someplace.
I have good luck at keeping the main damage inside
the cover.
The most common failure is the transformer. It
will either be burnt up or have an open turn. If it
is open, it is usually the wire that runs across
the top of the coil and not inside the coil.
Of course, it is usually the primary that is open.
I find that the turns ratio is usually a nice integer
number. In other words, for 120V input, it might
have 120 or 240 turns on the primary. Things like that.
If the primary is badly burnt, you can use the secondary
as a input ( from another AC wall wart ) and a few turns
replacing the primary to determine the turns ratio.
Also, be warned that the cost of the wire is often
more than the value of the wart, unless you have a
good source. If you have several scrap warts of the
same size, you can often swap coils.
