I noticed today that web sites that are screen width responsive and device
independent are also "responsive" to really old browsers like Netscape 2.0
running on a Windows 3.11 box. The whole push to make web sites mobile
friendly has had the unintended consequence of making Windows 3.11 web
browsing a little more practical than before. The only issue I found is
pretty quick as a lot of the overhead if not transmitted by the server,
perceiving the download is to a mobile or limited device.
If you get the chance and run an older browser on an older OS my site is a
pretty good example of a modern site design that works in Windows 3.11 /
Netscape or Alpha / Mosaic etc.

Hi people? I've installed SIMH on my computer and I want to get around
with the emulator for the pdp-10; it was a beautiful machine and the
ancestor of the GNU project, so is quite charming.
I have no idea on how to begin using it. Is the first time in my life
that I get in touch with something related to old computing.
I want to know where I can get software, TECO and adventure to mess
around (because of the importance of both); and, very importantly, how
to get this software running in the emulator.
I've been searching about the software and it's quite easy to get.
Hope my question doesn't bother people,

I've been having fun looking at TV programs that I watched when the
family had a 17" monochrome RCA set. At any rate, here's one such about
a guy who gets shocked by a computer:
Note that, about 3:20 in, the guy doing the troubleshooting on the
system pulls a faulty tube and gives it to his companion for
replacement. "12AY7" is what he says, but hands the other guy an octal
tube--the 12AY7 is a 9-pin sub-miniature. (TV had goofs even then).
Other than the IBM Model B electric typewriters, there doesn't seem to
be much to see. From 1955.
Here's another one from 1956:
This involves a mechanical translating machine that's been adapted to
diagnose and prescribe treatment for diseases. There, you can see the
same IBM typewriters, as well a couple of keypunches (IBM 024/6?) and
bunches of tape drives that I don't recognize. "Memory coils", anyone?
The strange thing is that years later, I met up with a fellow who had
worked with Gerald Salton on the nascent SMART system that, I believe,
eventually morphed into MEDLARS.
Stuff from a time when men wore hats and women wore dresses.

Try sending a message to Jim Leonard (trixter at oldskool.org).
He has done a lot of work with old PC graphics modes and might know about this mode.
When looking for Unix distro's for rhe PDP-11, I did find information
of how to make a System II using a Unix version 7 as it's base.
I also came across some hits about the existence of System 5 Release 1
for the PDP-11 (basically intended to be only for the 45 & 70).
On www.archive.org I did find both the System II and System 5 user
manuals, and the S5 manuals does mention the 11/70.
So, did it indeed exists and if so, is there someone who can help me
maybe with an image to run under SIMH?
Ik email, dus ik besta.
Having got 8/e (A & B) plus 8/f and 8/m into
production its time I made a few comments.
The aim has always been to reproduce the original panels using the
process DEC used all those years ago.
Needless to say we had to go through the learning curve with only
photographs, scans and one 8/m original
panel to go on.
In the interests of origiality I have kept what we used call 'features'
as found in the documentation and the sample we had.
I'm trying to reproduce the original, not produce an improved or fixed
The only process deviations I have allowed myself are as follows:
1. The original versions would have been drawn twice full size by
hand on matt paper in indian ink.
One sheet per colo(u)r would have been requred. They would
then have used a process camera
to reduce to one to one positive masters on clear acetate film.
The cameras (they were huge) and the darkend rooms they worked
in no longer exist.
I used to do just that in the early '70's but whats weird is
where I worked is less than 50 yards
from the silk screen studio doing the work now.
Now I use Inkscape and its layers to do the same thing. The
screeners have an Epson printer
the size of a piano to print my layers in black onto clear
film. After that the process is the same as it was.
They take a fine meshed cloth streched onto a frame. Its
coated (by hand) with a photo sensitive
emulsion, when dry it gets exposed through the master using
a UV light source.
The the parts proteced by black on the master are water
soluable and get washed out and hence
let the ink through. So one screen per layer is required
2. DEC would have printed the images first and routed or milled the
holes using some kind jig later.
As long as the hole stayed inside the white line that was
deemed to be OK.
We drill (laser cut) first and screen afterwards.
I restored my 8E cpu to running condition years ago, but never got around to
the rest of the rack. Mainly to reclaim floor space, I'm getting the
peripherals I always meant to go with that system into the dual rack and
wanted to ask a few questions...
Dual bay H967, items to go in are PDP-8E, PC04, TU56, RK05, and possibly an

https://www.flickr.com/photos/131070638 at N02/25152416940
But the rack has two nice looking doors, example:
https://www.flickr.com/photos/131070638 at N02/22605790200
(the TU10 and TM11 is being traded off, so the left rack in that picture is
an empty one now but I still have both "doors").
I'd like to keep the two doors, but will not be able to fit all the devices
above in. May just hook up an "external" RX02 (I have one in a DEC
roll-around cart), or perhaps one would fit behind one of those mustard
colored doors, I dunno. Hate covering a nice peripheral up behind a door.
Might put everything in the left rack, get rid of the bottom door, and just
use standard filler panels. Current plan is cpu in right bay, pc04
underneath. Left bay would be TU56 & RK05 (and RX02 if I lose the door).
What would you all do for something that is as period-correct as possible?
I looked closely at the sloped panels at the top of each cabinet. It looks
like the yellow trim/logo is actually a plate that slides into the bezel.
The one on the right is just yellow, but has a white border screened on it.
The one on the left has no plate, so it's just "white". What is the chance
that anyone has one of those yellow plates, perhaps one that actually says
"DEC" on it? I'd be highly interested. Failing that, at least one that
matches the other (yellow with a white border). Anyone have one laying
I'd have never thought I could run out of official DEC slides, but it
appears that I have (at least for older DEC items). I need to rack the RK05
and the TU56. On the RK05 - does anyone have a spare set of slides or can I
definitely just use RL02 slides (which I have lots of)? I have the wide grey
inner slides on the RK05 but no outers and I noticed just one of the inner
slides has a gold L-catch release on it so I'm wondering if there's anything
special about RK05 slides.
Thanks in advance!
I found switch levers and a mounting frame design (
http://www.thingiverse.com/thing:360853) that I would like to have casted
with molded-in color, close to the originals as reasonable.
Has anyone already done this that I can simply buy from? If any injection
molds have been built I'd love to put those to work. Would it be better to
just paint a 3D print of these?
Also has anyone created the front panel PCB design? I use EAGLE and would
love to at least have a CAD outline from which to start as I build my
emulated PDP-8/e. Pretty much like the SBC6120 but emulated on a 32-bit
micro as opposed to the HD6120.
I await your thoughts!

The canonical textbook is Ralph Gorin's _Introduction to DECSYSTEM-20
Assembly Language Programming_ (Digital Press, 1981). Lots of examples,
well thought out presentation.
It's a shame that Ralph's book has become so rare. (Seriously, who
does the seller asking $1,441.25 for a copy think he's talking to???)
Probably remaindered in the 1990s at any library that had a copy.
If you were near Seattle, I'd say make an appointment and I'd give you
an afternoon's worth of overview.

What is a techno-savvy student? Can classic computers possibly give an
answer? I used early microcomputers in my electronics classroom I
taught in the 70?s. Computers back then were rather primitive, not
much better than calculators, but did mimic human learning ? well
maybe not advanced enough to deal with calculus! But they did help
with the tedious tasks of generating random #s to start a particular
process - a game for instance. Maybe not intellectually challenging
nonetheless doing a required job leading today to sophisticated games
that do more than entertain. Back then students were put in groups to
build a work station employing a Commodore 64 or Apple II or Heathkit
H8. Fund-raising bought these computers at the school board was
reluctant to spend money and or political capital that only benefited
the few though we did install a workstation in the library ? what
wonder that created as it was small in comparison to the PDP-8.
So what is a techno-savvy student now: Conversant in using a
technological gadget to enhance his/her life? Or being able to build a
computing workstation in high school? Or for simply possessing a basic
understanding of how electronic/computing technology makes life more
bearable, less boring? I don?t have the answers though being 64 I?ve
lived through the evolution of computing technology and seeing how
it?s affected my life good or otherwise! Looking forward to using my
old computers, Coleco ADAM and Haethkit H8, if I can keep them going
by procuring parts, as my dear friend who has them works tirelessly
and I contribute when I get up to the big city in keeping them
functioning. Such are the joys of classic computing. :)
