I suspect it is a Macintosh utility (Disk Copy?) Lisas could run Macintosh software using something called MacWorks.

It's the MiniFinder - part of Macintosh System release 2, I believe.

So, the KT11-B Paging Option engineering drawings recently made their
appearance online:
http://bitsavers.org/pdf/dec/pdp11/1120/KT11-B_EngrDrws_Feb72.pdf
After a good bit of study of them, I have prepared a 'Technical Manual' for
the KT11-B, somewhat in the flavour of the old DEC technical manuals:
http://gunkies.org/wiki/KT11-B_Technical_Manual
since the prints, by themselves, are fairly inscrutable: an incredibly large
mass of gates (almost no MSI, other than a couple of Flip Chips included in
the drawings as modules).
The article basically attempts to describe how the thing works internally; it
includes sections which describe the function (i.e. point) and operation of
the circuitry on each page of the prints, and there's also a signal
dictionary which describes what all the major signals mean/do.
It's not quite absolutely complete, but it's 96% there at this point; I am
still working on it. One thing I do intend to add (when I can work it out :-)
is to annotate the table of states with info one what each states _means_.
If anyone is particularly interested in this device, and reads the article, I
would be very grateful for feedback on what's still missing that I could add,
suggestions for better organization, etc, etc.

As common as this monitor is, I don't see a scanned copy of a manual on any real site.
Anyone know of a copy?
I went ahead and bought a VM-4512 manual from Tucker to scan. At least that will be around..
Sir;
I working on a project to build a PDP-8i for a combined Compute
Science/Electronic Engineering course on design. The purpose of this
course is to teach the basic of computer design, build and Programing a
computer they must build. This course is still a year down the road.
I volunteer to accomplish the building of the prototype system using only
the parts available at the time the orginal computer were built.
The point of the build is, if a 70+ can sit down with the course material,
and design and build a working model of the PDP-8i, the there is no excuse
that each student attending the course, should not be able to accomplish
the same task.
1. I would like to know if you still have your PDP-8i Front Panel still
available?
2. What is the cost for the panel plus shipping to Tucson, Arizona?
3. I understands that you are attempting to re-manufacture the Switch
Rocker Assembly? And possibly the PCB board for mounting the switches?
a. If so, I would like to know status, and an estimated cost for a
complete set?
B. Would these items be compatible to with c&k 7000 u-frame series
switches assembly?
One other question I have is do you have any drawings that give both the
dimensions and profile of the mounting frame? If so are they available?
I want to Thank You for taking the time ahead of time in answering this
E-mail.

Hi Ray (and everyone),
I'm also very interested in knowing the mechanical dimensions of the front
panel PCB and positions of the lamps/switches/mounts/etc., but for the
PDP-8/e. Does anyone have front panel PCB dimensions and positions for all
the UI components I could use?
I can make a simple PCB design for each of the main areas (lamps, switch
register, other switch groups) that will arrive at a few smaller PCBs,
saving a ton of cost. I also have experience in LED display and switch
matrix design so we won't need a thousand wires going everywhere when used
with an emulator. For example, one USB cable for the entire front panel.
There exists the amazing PiDP-8 (
http://obsolescence.wixsite.com/obsolescence/pidp-8) that has all of these
items taken care of. But there does /not/ exist one for the PDP-8/e.
I await your wisdom,
--

I picked up a 700/60, the ANSI version of the HP 700-series terminal and when I took it
apart to clean, it had a VDC 1401DP31BE inside. I swapped the CRT into a 700/92 which
has a slightly different board, and a burned in amber tube, and it worked fine.
Also I noticed the 700/96 PCB is almost identical to the 700/60, so I'll try a
rom swap to see what happens.
Too bad there aren't generally available cross reference list for terminal CRTs.
FWIW, the 700/96 has a Philips M32ECD3G CRT.
VDC is having a "sale" on the 1401DP4 and P31. The tube price is pretty cheap but the
shipping is about double when you price it against their normal $55 price. The shipping
goes down with quantity, so if you buy 5 or so it ends up being about $25 a tube and
significantly cheaper than all of the ones listed on eBay.
Department of Defense Debuts Vannevar Bush Faculty Fellowship, Research
Grant Now Accepting Proposals
The Department of Defense (DoD) has announced a new competition for the
"Vannevar Bush Faculty Fellowship" in a recent Funding Opportunity
Announcement (FOA) (N00014-16-R-FO12) on www.grants.gov. This program is formerly
known as the National Security Science and Engineering Faculty Fellowship
(NSSEFF), and both program names will be used for this round of competition
during the transition phase.
The Vannevar Bush Faculty Fellowship program is sponsored by the Basic
Research Office, Office of Assistant Secretary of Defense for Research and
Engineering (ASD(R&E)). The Office of Naval Research (ONR) executes the
program for ASD(R&E) and is soliciting proposals. This program seeks outstanding
researchers to propose basic research that is potentially transformative in
topics areas of interest to the DoD.
?I strongly believe DoD faces some of the most exciting and difficult
problems to be found in research and technology,? said Secretary of Defense Ash
Carter. ?Vannevar Bush fellows will lead the way in transforming and
defining new fields of science and in helping the Department look to the future.
?
This new program name commemorates Dr. Vannevar Bush (1890-1974). He was
the Director of Scientific Research and Development during World War II and
the author of "Science, The Endless Frontier.? Bush was also a professor
and Dean of Engineering at MIT and later founded a large defense and
electronics company. As a devoted teacher, administrator and entrepreneur, Bush
made creative and innovative contributions to science, engineering and the
nation.
During World War II, Bush mobilized America?s scientific resources to
achieve advances in defense technologies that were decisive in winning the war.
After the war, he was instrumental in formulating sound policies for the
advancement of science, engineering and education.
Bush, in his famous 1945 report, "Science: The Endless Frontier,? wrote
that ?the pioneer spirit is still vigorous within this nation. Science offers
a largely unexplored hinterland for the pioneer who has the tools for his
task. The rewards of such exploration both for the nation and the
individual are great. Scientific progress is one essential key to our security as a
nation, to our better health, to more jobs, to a higher standard of
living, and to our cultural progress." For more information on how to apply,

The _first implementation_ may have been 16-bit, but I am in no doubt
whatsover (having written a lot of assembler code for the 68K family)
that the _architecture_ was 32-bit:
- 32-bit registers
- many operations (arithmetical, logical, etc) defined for that length
- 32-bit addresses
Etc, etc, etc, etc.
