"I found these manuals on ebay - I already have a copy of all of these, but I
thought fellow HP 2100/2114/2115/2116 collectors might find them usefull."
I've already scanned in these interface manuals, and am working through
a big pile of others right now.
I have a TK-50 with a tape stuck in it, it is malfunking :-)
I thought I would put it on my workbench and power it up but that doesn't
seem to leave it with enough smarts to load and eject tapes. Do I have to
hook a TQK50 to it? (I suppose I could bolt a bit of Qbus to a board with
power but I'd rather not if I don't have to.)
Is there a jumper/testpoint I can change to put it into "local loop" mode?

With the help of many fellow archivists, I've pieced together the
first hundred or so DECUS RSTS-11 library entries to form a neat
web-accessible archive.
These RSTS-11 library entries date from the early to mid 1970's, and
were originally distributed by DECUS on punched tape and
DECTape. Perhaps the most recognizable of the entries are
RSTS-11-13 and RSTS-11-14, collections of Basic programs from
David Ahl that became the basis of the famous _101 Basic
Computer Games_. Here you get to see the source code in its
original RSTS-11 Basic form, from an era before Bill Gates and company
began writing their first Basic interpreter.
These RSTS-11 archives are available over the web at
http://pdp-11.trailing-edge.com/rsts11/
As I sort the thousands of megabytes of RT-11, RSX-11, RSTS/E, and
other PDP-11 related material I've got in the collection and index
it, I'll announce progress in these newsgroups. If you're interested in
joining in with the effort, hearing about works in progress, or
making your opinion about the web indices known, you're welcome
to join the "pdp-archives" mailing list. Subscribe over the web

At VCC=VDD=5V the part would run all hte way to 3.2mhz. They claimed
at 10V it would 5-6mhz but don't believe it. I have one of the 10V parts
and the cmos is so slow that some of the signals come out a full clock
behind (and 155ns clock)! Keep in mind CMOS then was silicon gate and
something like 6-10micron rules, can you say SLOWWWWW. The SOS (silicon
on sapphire) part was a bit better. FYI: people that used the SOS part
werent going for fast as it's main appeal was low power (~10mw) and it
was RAD hard.

Not all *that* hard!

The RT-11 Installation manual is one place, the RX11 manual is another,
any of the "Microcomputer Interfaces" books that has the RXV11, ...

You could just, say, go to
ftp://metalab.unc.edu/pub/academic/computer-science/history/pdp-11/bootstra…
and fetch "rx01_boot.txt".
What are you going to try to boot in just 4K, BTW? I'm scratching my
head to figure out if even RT-11 V2 fit in that small a space...

On my web site, I have a paragraph or two about the EDWin NC package
that I'm using. In short, it has everything but the kitchen sink, but is not
terribly well integrated and requires too many mouse clicks to get simple
tasks done. To be fair, though, my speed seems to be improving with each day
that I use it.

>>Cool.
I may do it in PDFs instead or in addition to the DXFs. EDWin has a lame
printing system, so I'll have to see which one produces the best results.

No problem. I'll probably pick someone out of Nuts & Volts or Circuit
Cellar.

Someone moments ago made a reference to old Nortel (well, Northern
Telecom, back then) display phones, but I didn't realize what they
were referring to until I'd deleted the message :-/
If those are the little black-paneled phones with CRTs and slide-out
keyboard drawers, could you give me a model number? I've just realized
that that'd make the perfect kitchen terminal, and might keep an eye
out for them now, but it's awfully hard to search the 'net for
'nortel display phones' without getting bunches of current stuff.

I have had a similar idea, but for $200, I found a surplussed 486DX4 with
16Mb, a 540Mb disk, two PCMCIA, one ISA, all built into a wall-mountable
case with the LCD on the front. There is also an external floppy and
an IDE connector (once I've sussed out, the other I've passed on due to the
connector). It's ripe for Linux hacking, kinda like a laptop without the
battery or keyboard.

True. It's also possible to fit ancient Linux distributions onto 40Mb of
disk, but my record is 80Mb.

Ask me if I run RedHat. :-)

That sounds about right.

Unless you _like_ to swap like mad.
I've been playing with Floppy-based Linux boxes, primarily derived from the
Linux Router Project. My smallest achievement is a 486SLC board w/8Mb, a
multi-I/O card (for parallel), a NIC, no video and a Connectix QuickCam.
After the kernel loads, the one script snaps a picture, converts it to a
jpeg and ftps it to a spot on my web page. No hard disk. I even found a
case the size of an encyclopaedia, thus no room for the video card. Total
investment, $25 plus the cost of the camera.
I've been thinking of a similar thing for the wall-mount 486: boot from floppy
(or flash - I have an IDE adapter for an ATA card) and use networked storage.
I could use the internal hard disk, but I want an appliance that I can turn
on and off without worrying about filesystem corruption.
Anyway... massively off-topic, but fun.

Like trying to find a needle in a haystack.....
Would anyone know which handbook/manual the RX01 bootstrap loader is in?
I need to toggle in the RX01 bootstrap into a PDP-11/20 with 4K config.
If the bootstrap code is too long would anyone know if DEC distributed a
RX01 bootstrap paper tape version?
