Stuff I got today, some of it will be available for trade.
Data General blue rack
Eclipse S/120 cpu
3rd party paper tape reader
DG qfloppy 8" floppy drive
DG 6100 disk drive
DG 5821NT blue terminal
4 keyboards for 5821 terminal
DG terminal printer 1
Pictures are at www.ezwind.net/jwest/dgporn
Unfortunately the 5821 terminal is suffering from extreme screenrot. Most of
the stuff is fairly dirty on the outside but quite clean on the inside. I
also got the following DG manuals in case anyone is in need of copies:
System manual (log of config/mods, local wiring diagrams, some schematics,
PM's & upgrades, etc.)
Eclipse S/120 Diagnostic & Maintenance manual
Eclipse S/120 Computer System Hardware Reference
Eclipse S/120 Assembly Language Programmer's Reference
Programmers Reference Series, mod 6097/6098/6099/6100/6103 DG disc
Dasher TP1 Terminal/Printer User Manual
Dasher TP1 Terminal/Printer Operator's Manual
Technical Manual (6040-6043) Dasher TP1
Technical Manual (6040-6043) Dasher TP1 Field Service Maintenance Procedures
In addition, for some odd reason I got about 100 IBM sys/32/36 8" floppies
in two IBM logo cases. Some of them are still in the shrinkwrap. Then about
9 or 10 of the normal size 8" floppy disk boxes, each full of IBM disks.
Some are IBM microcode, some are IBM programs & utilities, most are
Also got the following IBM manuals:
IBM system/32 operator training book (includes sys/32 introduction, student
data disk, and two cassette tapes)
IBM system/36 system reference
Sys/36 system messages, vol1
Sys/36 system messages, vol2
Sys/36 RPG messages
Sys/36 Utilities messages, vol1
Sys/36 Utilities messages, vol2
All the ibm diskettes and ibm manuals are available immediately. I will keep
most of the diskette cases.
The DG stuff I'll keep till I do my DG refurb, then some of it will become
available, likely the S/120 cpu.

You should just image the disc, assuming you only have one shot
at reading the data, and mess with interpreting it as a second
Running an emulator with the necessary app, and screen scraping
may be necessary to recover content in some cases.
I should also mention that part of my charter is to build a library
of media and file formats (I need it to interpret the stuff in the
CHM archives) and to start putting together emulator suites for data
recovery and for use in Museum online and physical exhibits.
Anybody know what this is? I found three boxs of new 5 1/4" disks for one
today. I picked them up becuase they're 96TPI DS DD (aka DS QD) and I can
use them in my SB-180 puters and Nicolet DSO. I'm just wondeering about
the computer that they're supposed to go with.
I have two of these:
Each has a pair of PSU's in it. I assume for redundancy.
However, the PSU's in one unit are strappable 110/220VAC
while those in the other unit are 220VAC. <frown>
If the PSU's are just redundant and aren't actively load
sharing, then I *should* be able to swap one 110/220VAC
for a 220VAC and run each array off a single supply
(taking care to hack the sense signal for the second
supply so the array doesn't continually report a supply
Am I missing anything here? Granted, the two supplies
possibly *do* share the load as a side-effect in normal
operation. But, I assume the intent was for a single PSU
to be capable of powering the entire device in the event of
a failure in the "other" PSU?
I have connected the Kennedy 9100 open-reel tape drive to my 11/84.
The interface board is the TC131. It sits in a UNIBUS slot, and the 3
cables are wired to the tape drive. The NPR switch is set for that slot.
I can mount a tape and after pressing "LOAD", the tape is moved to
load point, after which I can by pushing a button set the drive on-line.
So far, so good.
When I boot RT11, I see (with .show dev) that MT at 172520 is installed
however, MS at 172522 is installed too!
Using RSX11 (show aco) it lists: MTA - CSR 172522.
That seems like a conflict to me: MTA (172522) and MT (172520), where
at 172522 would be MS ...?
As this is my first actual use of tapes, this is my first puzzle.
Next: suppose I mount any tape (contents unknown and irrelevant), which
commands could I execute?
I tried the following (excuse my stupidities) under RT-11:
.dir ms1: --> returns: ?MON-F-Dir I/O err - 011020
.init ms1: --> returns: ?MON-F-Dir I/O err - 014740
is this meaningfull to somebody? Should these commands execute correctly?

I recently picked up an 11/73 [M8190 / KDJ11-B in a BA23] and when I
finally got around to powering it up today it was failing test 61 Line
Clock during power up.
I found some info on the H7864 power supply in a uVax doc which says
that the BEVENT L signal from the power supply is enabled by the LTC
swtich on the control panel PC board.
I couldn't find any docs with details on the 11/73 control panel PC
board. I can see a three header pin jumper, which has two of the pins
jumpered together, and a dual rocker switch. Does anyone have docs
for what these jumpers / switches do?
Through trial and error I found that flipping the first rocker switch
made the test 61 Line Clock failure go away, but for future reference
I'd still like to know exactly what the switches and jumper are
supposed to do.
I too, am looking for info as to how to use one of
Did you ever find a manual?
Any help would be appreciated.

Hello list members,
I've got an mid-80s SGI IRIS in my collection, an IRIS 3130 in Control
Data skins. What I'm looking for are boot or installation tapes that
allow me to rebuild a working OS installation on one of the more or
less compatible ESDI drives I've got.
If someone can help me in this task, that would be greatly
appreciated. When I started out with SGIs I almost didn't expect to
ever get my hands on an IRIS 4D... a *real* IRIS was beyond all
I've got some kind of inventory and dark pictures of the box online:
For some better pictures have a look at Kayas "obsolete hardware"
Both IRISes are actually only one machine. On a related note it would
also be nice to hear from other IRIS owners in Europe. So far I know
of NO OTHER rescued IRIS around here which is somewhat sad, if you ask

true of circulating libraries. These have limited space. While most librarians would like to be able to keep
everything, you do that at the expense of patron's ease of use and "relevancy" of the collection. If people walk into a
library and are confronted by scores of books that you are not at all interested in, they tend to give up and leave.
What you want is an archival or academic library. The maintenance of a large collection is integral to the operation of
these libraries, and they are unlikely to wantonly cull books.
All libraries have a focus. If you disregard the focus it is unlikely that they will be very interested in your collection.
OTOH librarians are "information professionals" and recognize the value of information. Ask (a MLS librarian)
and they will probably direct you somewhere where your collection will be used (provided they aren't rushing
around - library directors are finding out that nondegreed paraprofessionals are cheaper, leaving more work for the MLSes)

Key word is city. Larger county and multi-county systems are doing O.K. Not that long ago, Washington had a proposition to
eliminate a library district (to "reduce taxes") go down in flames.

And you discribe the reason for the existance of most government programs of any value.
IRIS x000 series seem to have problems with those junky encapsulated paper caps that like to die.
Short answer on how to get the PSU out: take all the skins off- through the top undo the wire connectors, the left-side has the bolts securing the PSU holding
plate to the chassis, the right-side has an access port.
The caps can be replaced with Mylar units fairly easily.
