There lie the next questions:

What is the base/emitter voltage for the ON case and OFF case?
How much current does it handle in circuit?

I have an Informer portable terminal. I can't verify the model number because
mine is in storage, but what _I_ have, emulates an IBM 3274 w/attached 3270.
You can also daisy-chain several of these terminals together and only the
first one acts as a terminal controller - the rest are dumb terminals.
I got mine at the Dayton Hamvention about ten years ago when lots of them
appeared at several booths simultaneously. It is _not_ an ASYNC ASCII
terminal.
It is _not_ VT100 compatible. It is a genuine IBM SNA PU Type 2. We used to
compare its behavior on an HP Line Analyzer to our own SNA product. It helped
us find a couple of bugs on our end during the BIND.
Theoretically, you could aquire the Linux SNA package and attempt to use it
there, but I know I'd have to have one compelling reason to try. If you
happen to need to dial up a 4331 or 4381 Mainframe, *this* is the tool.

I will say at the start that I have no experience with the 5XX (7013) - all this
is based on the 320 and 375 machines (7012) we have at work.
The serial ports on the 320s (can't remember about the 375) are indeed 10 pin.
Physically it is the same as on the IBM 6150 but I haven't got around to testing
the adaptor on my 6150 yet.
If you want to try the expensive route, the part number printed on the adaptor I
just pulled out of the draw is 00G0943, and you can try IBM. If you want a
cheaper route, with luck we will be decommissioning and selling off the RS/6000
stuff within the next few months (only one piece of software left to be ported
and that is almost finished) and I'll see what I can obtain for you.
Video IIRC is a DA shell with three miniature coaxen in it, so I imagine Peter
would have spotted it if it was there! The monitor is the IBM 6019.
(My plan is: build one working 320 out of the two dead ones, and sell: a
working 375, with monitor; a working 320, with monitor; a dead 320; a spare
monitor. I have no idea how much the dead 320 will cost to repair, but if IBM
are involved it is likely to be prohibitive, so perhaps I might get you the
video card from the 320)
BTW in case you wondered the keyboard is _not_ PS/2 compatible, but the mouse is
and all the windows drivers think it's a Logitech (it's on my PC at the moment).

I came across two terminals that look like they are portable. Labeled
Informer model 207, the keyboard is in the cover of the display and clips
to it with two metal clips. There is a fold down handle on the back and it
is covered by a canvas dust cover. There are connectors for a phone
connection and external keyboard on the back. It looks like some sort of
troubleshooting terminal. I have searched the Web and only found 1
reference. Most of the incorrect references are to French terminals. Does
anybody know anything more about them?

Hi to everyone.
I'm no longer a member of the list, but some of you will remember me :))
For personal reasons, I'm currenlty offering my entire collection of
collections for sale. I have some quite interesting vintage computers -
including the beautiful Datanumerics DL-8A (a front-panel switch 8080 beast)
and a homebrew S100 system with a Signetics 2650 processor emulating 8080.
Also, rare home computers such as the Hanimex Pencil II.
I am also selling my entire collection of Soviet Calculators (some 100
units), but only as a whole collection.
I will be delighted to do photographs for any interested purchasers.
Thanks for your interest - the URL is in my signature, below.
Cheers

I just aquired and IMS inc multiuser S100 system the suize of a coffe
table. To restore it I need docs/info. It appears to be a complete
system.
It has 4 Commercial Dynamics Z80 slaves {SCPU MK4cr ISS 1}
1 IMS cpu card {A644}
1 IMS 64k dynamic ram card with parity. {c00464}
1 floppy card 8" 765/8257 based, S8000 floppy control {c00401}
1 WD controller for 8" wini (IMS) {A821 2562-1}
1 IMS I/O board, 2 serial using 8250, parallel using 8255 {A631}
Anyone with docs for any of the boards I'd like to talk to them.

The V6 and V7 images currently available have device drivers that
were built for Unibus systems. They expect a Unibus Map to be present
for accessing memory above 256Kbytes (many of the drivers were built to
always expect a Unibus map). The "safe" thing to do on a Q-bus system
(or an emulated Q-bus system, like Supnik's emulator) is to run with 256Kbytes
or less.
(Even that isn't perfectly safe, some of the tape drivers simply refuse to
work with a Unibus map no matter how much/little memory is there.)
(And yes, I know there are Q-bus systems with Unibus maps, but I'm ignoring
those right now.)

BSD2.11 does need separate I&D, but V7 doesn't. If you don't have separate
I&D, ISTR you need to build it for "small machine", and it runs a bit
slower.

I tried swapping my M8186 (11/23) for M8192 (11/73) but it doesn't run.
Maybe I need to rebuild the kernel (I've got an original distribution, not
one of the images from PUPS), but perhaps it would work with more memory or
by swapping RLV11 for RLV12.

While moving and sorting through the last of the books and magazines from
our old house, I found my long-lost copy of "Finite State Fantasies", a
semi-educational computer cartoon book that I bought in a Byte Shoppe about
25 years ago. It's kind of cool and funny, and I would like to scan it and
put it up on my web site for others to enjoy, but I don't want to whiz in
anyone's Cheerios in terms of copyrights. I have done some web searching,
but couldn't find any current contact information for Richard Didday (is he
still around?), Matrix Publications (whose name appears on the copyright
statement), or Dilithium Press (who, based on my searches, seems to either
have been the precursor or the successor of Matrix). Does anyone have any
information on any of these folks, so I can try to get their permission to
scan and share this strange book?
