That's out of my area but a quick check of the 3490 manuals I could find
(couldn't find any relevant 3480 doc) does not look good. It says this is
a "call your service rep" type of error- the CHK XX codes are apparently
undocumented, at least for 3490s. If you can't find a 3480 guide on
bitsavers (I just checked and couldn't find one) then this may or may not
be worthwhile:
http://www.fujitsu.com/downloads/COMP/fcpa/tapes/m2488ce_prod-guide.pdf
The only reason I suggest it is Fujitsu has some history of ripping off IBM
(they did it with several OS versions and paid over 800 million USD in a
settlement) and compatible-hardware manufacturers often try to keep the
same error codes to make pubs easier (also by ripping off IBM), so maybe
just maybe they are using the same codes as the 3480/90 tape subsystem. See
appendix E. for the code listings.
Nice piece of hardware btw. IBM's marketing materials say "The A22 control
unit is priced at $65,430, and the B22 tape unit, which contains two tape
drives, sells for $43,120."
Good luck and post back if you find anything. If you don't get any answers
>from the list or elsewhere (some good places to ask are on IBM-MAIN (you
will need to subscribe or nobody will see your posts) and the yahoo
hercules groups) email me offline and I'll see if I can find anything.

OK, so someone gave me a nice 40U equipment rack. I was planning on
using it for my Nuclear Data ND812, which has rackmount plates for
everything. I first experimented with the empty dual 8" floppy rack
unit and a couple things came up.
For reference take a look at these photos to see the ND812 rack units:
<http://picasaweb.google.com/legalize.slc/NuclearDataND812#>
First, I'd like to minimize the potential for scratching the paint on
the rack mount plates. Should I use a plastic or teflon washer between
the plate and the mounting screw? Like most rackmount equipment, the
only support is from that front panel, so it has to be mounted pretty
tight to support the weight.
The maintenance manual doesn't say anything specific about mounting the
equipment in a rack. Is it typical for things to be supported only by
that front mounting panel, or do people add some kind of additional
support in the rear?

You can see an anti-tip bar here:http://www.flickr.com/photos/textfiles/3789164168/
If you look at the bottom of the rightmost TU80 you can see a silvery T-shaped thing with a foot on it. That is the anti-tip bar.

I had one just like this back in the day with full graphics , mouse etc
that I used as a workstation. I upgraded it from MV-11 to MV-III in box
with the above kit.
Nice versatile units and I hope they go somewhere they can be used.

I can't help you specifically but I note that that tape would've held some posts from mid-1990 and want to wonder out loud:
Wonder if the same posts were on the "Usenet CD-ROM's" that were sold (or maybe just discussed) in the early 90's.
"Sterling Software" is one name associated with that but I also remember a Vancouver BC based company doing similarly.
Likely I just replaced an unreadable tape with an unfindable CD. I have no idea if the "sell-usenet-on-CD's" ever actually sold any.
Tim.
With the addition of two more Tektronix 4015-1 terminals, I've
rearranged my Tektronix storage tube terminals in the warehouse and
uploaded some updated pictures of "Tektronix storage tube row". (The
4015-1 is essentially a 4014 with APL and printer interface options.)
Neither of the 4015's are reported to be in working condition from the
seller, but at least all the keycaps with APL glyphs are present. The
4010 and 4014 are relatively simple terminals, so I should be able to
restore them to working order. They have no microprocessor, firmware
code or custom ASICs, so repairing them should be a matter of
replacing capacitors or replacing TTL or analog parts.

Hunter S. Thompson once said; ".... but once you get into a serious drug
collection, the tendency is to push it as far as you can..."
My drug, of course was classic computers. I shared this "hobby" with my
father, whom was retired USAF and retired TWA aircraft mechanic. We would
tinker with all sorts of stuff we collected and finally when we had no more
room, built a small storage shed.Then a few more, until we had about 2-3.
When I had to downsize because of the economy and moved, I stored my
collection inside the various sheds we built on his large parcel of land in
the Sonoran dessert, Putting them away when we finished or stored them to
await further restoration. I don't know how many pdp's or HP we restored or
fix to working condition, then gave away to students in the area. I was the
bigger collector though. I was most interested in all the DEC stuff we got
at auction for next to nothing; alphas, vax;s the occasional pdp's. But I
also collected anything that was "pre-80's'
Well, my father passed away last month. We had already stopped working on
stuff when he was diagnosed with Alzheimers. I would always be back at the
shed picking through stuff for my projects. Unfortunately, much of the stuff
that was well-ordered and nicely on racks, etc was taken doen when my dad
would be searching for stuff and couldn't remember what he was looking for.A
lot of the stuff was "reordered" and some "lost" or stored in one of the
sheds that lost it's roof in a fierce storm and was all waterlogged. But a
lot is still OK.
It took me only a few days recently, to realize, that I should be thinning
this heard down.
My mother may decide to move as she gets older and I cannot move all this
stuff to storage.
Much of it is commodity stuff. By that I mean it was part of the "lots" we
would buy at the university auctions. For one item we wanted, we had to but
the whole lot. Much was discarded, but some of it still remains. Sun and SGI
stuff, older HP stuff.
The stuff I valued, DEc stuff and my pre-80's stuff too need to be taken
care of. I have decided to "sell" a bunch of the stuff. Those that will
still fetch a decent price on Ebay. Most of the money will go to my mom as
her income has been greatly diminished by my fathers death. And besides, she
put up with us for all those years. Other stuff, I'll sell to anyone
interested in throwing a few buck my way. A lot of stuff is just to be given
away.
So I"ll be doing triage at first. It is getting "warm" here in SE arizona,
on it way to HOT and I'll be doing triage slowly, in the morning and it will
take months.
There is a lot of stuff I'll give away to anybody that wants it, some is in
great condition, some terrible, I'll let you know which.
I have lots of odd cabling and lots of odd stuff.
If you are looking for something. let me know.
I also have lots of documentation and some of it I know Al Kossow was
interested in.
I soon as I find a cheap/fee web space. I'll start posting what is
available, rather than cluttering this mailing list.
But here are a few things:
A complete IBM RT system (romp processor) with most/all the software and
documentation. A couple of AT&T systems, a "lot" of qbus pdp and vax stuff.
An 11/04 unibus system with third part floppy's and an TV07 tape drive (
tape drive complete but not functioning) along with the "PDP" rack it's in.
A Tektronix 4051 computer, a OSI superboard, a few HP 9000/300 systems. Lots
of tabletop vaxes and alphas. a lot of vt 520 terminals, as well as some
ADM-3A, VT100's, Vt 220. Vt 320''s and other odd terminals.
A few of the Qbus Mac cards.
If you are near Tucson Arizona or are coming to the area this summer, you
may be able to pick it up in person, or maybe pick through all the stuff.
This is not a fire sale! I have decided to let it go slowly as the day may
come where I would have to get rid of it fast, but not now. But I'm ready to
deal and while most of this stuff isn't really rare and expensive, it;s
still worth a few sheckles to collectors. and the money's going to a good
cause.
Cheers

Hi guys,
Here's a screenshot of the analysis side of the current DiscFerret
software build:
http://i162.photobucket.com/albums/t242/philpem/Screenshot-1.png
At the moment, I've got it reading IMG files (the format of some disc
images Chuck Guzis sent me a while back). CWI files are next on the hit
list (another one of Chuck's file formats) and then DFI files (the
DiscFerret native raw image format).
The GUI was built with wxWidgets, and in theory the code is completely
cross-platform compatible. I'm aware of wxWidgets backends for GTK, Mac
Cocoa/Carbon and Windows, so that covers all the major *nixes, OS X and
Windows. As long as you have a half-way decent C++ compiler, that is
(*cough* GCC). However: I will openly admit that the code has only been
tested on Linux.
It slows down to an absolute crawl (~60 seconds refresh time) if you
turn anti-aliasing on... though I suppose that's to be expected when you
ask it to plot 30-odd thousand data points on a scatter chart...
The raw-reader app is working too -- I can specify the various
parameters of a disc drive, and do a full track-by-track read of an
entire disc, and dump the data into a file. Next on the 'add list' is
DFI support (so the analyser can read it, of course!) then disc-format
script support.
Effectively, I want a tool which can be told what type of drive is in
use, what disc format, and will automatically figure out whether
double-stepping is needed, and what read parameters to use. Even to the
point where it'll warn you if you specify a 100tpi format and a 96 or
48tpi drive... Built in sanity checking :)
Which now brings us onto naming -- the reader app currently calls itself
"discferret-read", and the analyser "Merlin". Can anyone think of better
names for these, or should I be lazy leave them as-is?
(Suggestions on an email to the usual address please!)
At this point the reader app is close to releasable (involving maybe a
few more weeks of work assuming I find a ready supply of Round Tuits),
but the analyser needs a lot more work. Mainly because I seem to be
spending a lot of time chasing mismatched-free bugs in the algorithms.
Thank $DEITY for Valgrind (and a great big sarcastic "gee, *thanks
guys*" to the GTK developers who have obviously never heard of it, much
less used it on their own code...)
Cheers,
--
Phil.

We (RICM) have an 8/I with 5x TU55 drives, a pair of bare 8/L, and a
very functional 8/S that now runs FOCAL.
I can give plenty of advice on ferroresonant power supply capacitors.
Advice is easy to supply.

Tom, I'm very sorry to hear your dad passed away. That's a hard lesson for
us all that the real classics are people, and they can't be replaced.
I would love to see all the machines and parts you have collected over the
years but I am a million miles away and had a recent personal "economic
downturn" that leaves me happy to have a roof and a piece of bread.
Good luck to you and your mom and I hope whatever else you have to part
with won't hurt nearly as much.
