How to Use This Listing
This catalog was assembled from information contributed in response to
my requests over USENET. I have tried to leave the information alone,
but make the formatting constant. To save editing chores, there are
several listing groups which share some common information. Each major
listing is separated by a line of '=' characters beginning at the left
margin and continuing for 70 characters. Within major listings,
sublistings are separated by a line of '=' characters beginning one tab
stop in and continuing for 54 characters.
The order presented is pretty much the order received, except where
oversights on my part necessitated moving listings to the end to avoid
disturbing the numbering. Each listing is numbered, and some summary
information presented under "Summary Information".
If you want to skip to some numbered listing (say 34), just search for
/#:<TAB>*34$/
using any editor which supports "ed"-style regular expressions;
the number always appears at the end of the line. The regular expression
/^Listing #:/
can also be used to skip to the next listing.
I have also tried to catagorize devices into broad categories, such as
"disk subsystems" for easy reference in the "Summary Information"
section.
Editorial Policy
All contributions will be accepted. I try to leave the submitted
contents completely alone except to present a consistent format. My
notes are enclosed in square brackets (``[]''). I obviously can accept
no responsibility for the truth of any assertions contained here.
Entries listed as available may have been withdrawn, or individuals
listed as contacts may have moved.
Please use the format presented here as it makes my job a lot easier.
Also if you give network mail addresses for UUCP, if possible specify
several paths. It is always a good idea to include a U.S. Mail
address and phone number.
Any additions or corrections received will be incorporated in future
revisions. ALL contributions will be acknowledged; If you do not
receive an acknowledgment in a reasonable period, please re-send.
Any contribution, unless otherwise specified, will be made available
to any responsible newsletter for publication. This listing has
already appeared in ";login:" and the European UNIX Users' Group
newsletter.
Suggestions For "Shoppers"
If you send network mail to people listed here for information, it
is best to supply several return paths. I have had several requests
which I could not answer because mail would not go the return path.
Giving your phone number is also an excellent idea.
Revision Date
This listing reflects all submissions and corrections I have received
as of November 21, 1983. It is essentially unchanged from the last
posting of May 16, 1983. I am eager to hear about new drivers, especially
for 4.2.

Caveats: I think Xylogics has discontinued production because
of reliability problems... but I can say that once you
get a good board set (it took us 3 mo.) then it runs
fine. The cute thing about the controller and drivers
is that they support multi-porting of the controller.
The controller is connected to as many as 4 couplers;
the couplers sit in the various Unibi and the
controller has its own backplane and power supply. We
boot a VAX and a PDP off the same disk and controller.
Miscellaneous: By the way, the 4.1 driver was adapted by Rusty Wright
of the Center for Music Experiment at UCSD from the up
driver and the 2.8 driver has an odd pedigree which I
don't remember just now. The 4.1 driver has fixed an
apparent bug in the up driver whereby on systems with
more than one drive on the same controller the "wrong"
drive queue will occasionally be linked into the
controller queue... sigh. Standalone boot drivers,
bootblocks and even VAX 11/750 ROM code available on
request. Other people at UCSD may have different
versions of this driver but I have gotten the impression
that ours is the only version that works (it may be that
ours are the only controllers that work(!)).

Device Name: Britton-Lee IDM 200 and IDM 500, speaking to the
host via a serial (RS232) port or a parallel
(IEEE488) bus utilizing a National Instruments
GPIB 11-2 card.
Device Type: The IDM 200 and IDM 500 are compatible Relational
Database Machines. They run a complete database
system (essentially a superset of INGRES) in a
backend processor, thus offloading your host of
the database grunt work. They communicate with
your host via either an RS232 port (speaking to
a standard device, e.g., a DZ11) or an IEEE488 port
using the National Instruments GPIB 11-2 UNIBUS
card. Multiple hosts (possibly running different
operating systems or on different processors) can
use the IDM simultaneously. SMD compatible disks
plug directly into the IDM. Up to sixteen disks
may be plugged into a single IDM 500 (four disks
for an IDM 200).
For CPU type: VAX and PDP-11.
For UNIX type: 4.1bsd, V7, 2.8234612346bsd (coming), 4.2bsd
(planned). We can also put you in contact with a
group doing System III support.
Availability: Available to anyone with the appropriate UNIX
license.
Terms & Cond.: The driver comes on a distribution with a complete
set of support software (ad hoc parser, embedded
query languages, etc.) for some amount of money --
prices depend on configuration, etc.

Caveats: This driver permits transfers between two DR11Ws
connected back-to-back. In our case it is used
for data transfers between an 11/34 and a VAX.
It is single use - no virtual circuits or other
fancy stuff. If anyone is interested in either

Comments: We have two versions of the driver. The plain version
looks like a fairly normal device. The protocol version
is intended for use with a packet switching daemon. It
allows only one open, reads whenever it is not writing,
and sends a signal when a read completes. The protocol
version requires some simple kernal hacking.
Bugs: The megalink is a real pain to use and doesn't work very
well.
======================================================================
Listing #: 44
Device Name: Tty driver
Device Type: Replacement for V7 tty driver
We have completely rewritten the V7 terminal driver for our 11/70. The
major objects of the rewrite were to improve the user interface in general
and to add support for Digital Engineering's "retrographics" upgrades to
Lear Siegler "ADM-3A" terminals. This software is not easily portable to
other systems, but we feel that our functional modifications could easily
be fitted into a traditionally structured terminal driver. (This is
likely to happen locally during the next 9 months as we add a new machine
to our system.)
Alan Hastings described our driver to several people at last summer's
UNICOM. The following is a brief summary of current capabilities:
- several control characters have been added to improve input line
editing. The "erase" algorithm is much smarter in regards to
control characters and tabs, which are properly erased from the
screen. CTRL/R reprints your current input line to make it easier
to see what you've deleted on paper terminals.
- added CTRL/O (flush output buffer) to CTRL/S and CTRL/Q. There is
an additional ioctl call to cancel the effect of this character in
appropriate situations.
- all control characters may be remapped or disabled with ioctl.
- typed input can be echoed immediately (UNIX default) or held until
the next read is posted (VMS default). Some users like this feature,
some don't.
- mode bits (like RAW) have been extended and made considerably more flexible.
In several cases, there are separate bits for input and output mappings.
This makes the driver much friendlier towards peculiar terminals (and
microcomputers emulating terminals). In all cases, the conventional
stty/gtty calls produce the conventional effect.
And, most important:
For each terminal on the system, there is an appropriate /dev/ttyxx entry
and a /dev/tgrxx entry. There is also a /dev/tgr (corresponding to
/dev/tty) which refers to the user's own terminal. The tgr devices accept
graphics data in a simple device-independent format and produce a correctly
merged output stream which keeps track of the terminal mode. Simultaneous
text and graphics use is fully supported. Interrupts and errors can not
leave the terminal hung up in graphics modes. This feature is a big help
in a college environment where many students without other computer
background are using the machine to analyze lab data.
We do not have this software available in a prepared distribution form, but
are willing to send it to anyone who's interested. Contact our system

Caveats: There is user level code to go with this. There is some
documentation. The package is not very professionally finished;
unfortunately, the hardware broke during conversion to v7
and stdio, and I left the institution, and no one else has
taken up the work. I have done some work remotely, and
written a fair amount of documentation on the package, but
it's not complete. You may be able to get something working
almost immediately, but there will be work involved to bring
it up cleanly.

Computer Vision Lab Drivers
At the Computer Vision Lab (CVL), several device drivers have been
developed for use on the Lab's PDP-11/45 that has run both versions 6
and 7. Those devices that are currently supported by version 7 have
been made to run under BSD 4.1 on a VAX-11/780. These drivers are
distributed as part of the ULISP (a LISP interpreter for PDP-11s) and
Computer Vision Lab image processing software tape. This tape, written
in "tar" or "tp" format at 800BPI or 1600BPI, can be obtained for a
$100.00 handling charge and agreement to a copyright license from the
