Sir,
I am following up on a query on the following link and am hoping that
you may be able to help...:
http://www.classiccmp.org/pipermail/cctalk/2003-September/026900.html
Within our organization , we use a number of 9-track Digidata Mag Tape
Units, Model P/N 1149-8-2-120-FN-UL.
We have some vendor service manuals for these, however what we have, do
not have any information regarding how to perform or check head
alignment.
We are looking either for a manual addressing this head alignment or a
"service agent" that has the capability to repair / align these units..
We have tried Digidata themselves and they have no information. I am
assuming someone somewhere has the capability / and or knowledge to
repair them and am looking for a contact
Any suggestions ??
Thanks for your help.

Hiyas,
Anyone here familiar with early history of DEC's moving from Ultrix
to the "new" system called OSF/1 (which itself was based on Mach) ?
I found some interesting docs from that era, and some of the dev't
cycles arent clear to me.. some help would be useful in understanding
what went on then..
Cheers,
Fred

I had the same problem on my Teac FD-55GFR 5 1/4" Drive, as I was trying to
recover some old applications of mine. Here are some advices:
1. Check if the BIOS setting is correct (1.2MB/5 1/4")
2. Check if the jumper configuration is correct - you can find that at:
http://www.teac.com/DSPD/pdf/5fd0050a.pdf
3. My problem: the spring that holds the head #1 on the disk surface
probably "got old". If this is the problem, try to press it gently onto the
disk, and push it twards the tracks at the end of the disk (the center). If
this was useful, I would appreciate a thank you mail... just kidding ;).
Went to a surplus store today and found a package that said that it was
"MOS Operating System" and that it was a multi-user system and that it was
MS-DOS compatible. Does anyone know anything about it? I've never heard of
it before. The package was sealed so I couldn't open it to read any details.

The technical manual is hosted on Terry Stewart's great System 80 site
at:
http://www.webweavers.co.nz/system-80/manuals_technical.htm
The site has the manual with the copyright owners permission which
includes the schematics.

Mike,
I just found you message about having the ciruit diagrams for a Disk
Smith System 80. I found one of these the other day in a recyling center
and always had a soft spot for them as it was first computer. The one I
found works, but has a problem in the video circuit. It is repairable,
but would be a lot easier if I had schematics to work from (I collect
video games from the same era as well so my skills in repairing these
would help me a great deal :) If you have a scan or even a photocopy of
this manual, I would glady purchase it off you.
Cheers, Geoff
Some of you will remember a thread earlier this year, in which various
of us discussed the ARM Evaluation System -- an ARM Second Processor
for a BBC Microcomputer -- and bemoaned either our lack of discs, or
that we had a Disc 1 that was corrupt.
Well, thanks to a kind benefactor who provided me with an *un*corrupt
Disc 1, I've been able to copy them and make them available on my
website. If you have an ARM Evaluation System and need the software,
go to
http://www.dunnington.u-net.com/public/BBC/ARMeval.html
What's there are ZIP files; I thought about making disc images, but I
can't get Xfer to behave :-( However, the discs are just normal ADFS
discs, and my webpage has links to the things required to unpack them
on a Beeb or an Arc (or later RISC OS machine) so there shouldn't be
any problem. However, if anyone on the list deperately needs actual
discs,
and can provide me with suitable blanks (5.25" DSDD or 3.5" DSDD, not
HD), I'll be happy to make copies.
Apologies to those who're on both the BBC Micro list and the ClassicCmp
list, and get two copies of this. To those who're on both *and* in my
private "ARMeval" list, well, good things always come in threes :-)

Hiyas,
Nyone here (relly) familiar with these beasties? I now have two
sets of them, and gawdamit, they dont talk together. I have one
set being the DEIRB-AG (my first set), and the set of new cards
are DEIRB-DA's. Cant yet tell whether its the cards, their
firmware or the drivers. Although... I tried one of the DA's in
my access point, and that one doesnt seem to be too happy with
the card, either, so it could well be the card or its firmware...
Any clues?
(yes, all cards are labelled 2400/FH, by the way ;-)
Cheers,
Fred

I would pay up to $350 for such a thing (it sounds too
perfect). I've been looking for it in the form of a "scissor jack" >>
take a look at globalindustrial.com
