Strange question, does anyone happen to have the keyboard overlays for the VAX/VMS version of Word Perfect that they can photograph, or better yet scan? I have the manuals, and the green, red, and blue stickers on the VT keyboard, but no overlays. I *might* have the overlays, but I can?t find the the VT keyboard I?m thinking of (though after digging, I know I have more than I thought).
I?m looking for the VT200/300 version (which should work for my LK401).

Vince,
I recently had Shapeways 3D print some of your card handles in Nylon 12.
They call Nylon 12 ?versatile plastic? on their web site and they use a laser sintering
process for fabrication. I used the card handles on my QBone and UniBone boards
which makes them MUCH easier to insert and pull. The Nylon 12 seems to be
quite tough and I used 3mm x 6mm long screws to fasten them. Shapeways
charged $5.00 each plus shipping to make them.
Thanks for the great 3D design!
Best Regards,
Mark
Re:
Today I finally got the SPACEWAR version for PDP-11/10 running again
on my PDP-11/05 with AR11 board.
...
Bill Seiler and Larry Bryant wrote this version in 1974
Congratulations!
Odd coincidence, sort of, in names ... "Seiler" wrote SPACEWAR in 1974 for
the PDP-11, "Sieler" (me) wrote it for the Digital Scientific Meta 4 (an
IBM 1130 super clone) in 1971. I suspect he gets his name mispronounced as
much as I do :)

Okay, now that my 11/45 is up and running well, I could really make good use of one of those rack caddies for RK05 packs to hold my most commonly used system packs for different operating systems. Anybody have one they'd be willing to sell/trade, or at least the DEC part number so I could try to track down some drawings?
Looking at pictures on the web, there seem to have been at least two styles: one with plated rod wings, and one with sheet metal wings? I'm supposing I'll end up needing to fab something myself unless these are less rare out there than I think they are (I've yet to see one go by on ePay, for example.)
cheers,

I did get it running on mine for a while. I remember it wasn't fast and
was kind of annoying - the VMS-capable SRM had a peculiar bug where if
the NVRAM battery died you had to failsafe-load the official Multia
firmware then load the VMS-capable one otherwise the framebuffer would
never initialize, not even after the battery was replaced. Finally got
a DEC 3000 and passed the Multia off.
Wish that some of the DEC gear that was showing up was nearby... ah
well.
Thanks Mattis - watching an AR11 making that
oscilloscope display brings back a lot of
memories from my PDP-11 programming days. Had
heard of spacewar in 1980, but was more
interested in playing around displaying data on
screen of a scope. One of my jobs was to clean
up electrophysiology data for publication and
that meant removing noise in signal so had a
joystick system which could move and click on
point on screen I wanted deleted. 11/34 was fast
enough that we had an EE summer student create a
dot matrix character set so we could put captions
on our oscilloscope images. Of course, only way
of getting hard copies of those was with an oscilloscope Polaroid camera.
Looking at the printouts that you're dealing
with, I had a hard time making out some of the
characters. Can see individual dots in a number
of the characters and haven't found any OCR in
past that works well on them. Had my MSc thesis
printed on and IBM lineprinter and looks good
>from afar but couldn't get any OCR program to
digitize it properly. At least the spacewar code is relatively short!

I managed to bring another one of my supercomputers back to life: an Intel iPSC/860. This one has 16 compute nodes, 8 i860?s and8 i386?s with Weitek co-processors, as well as 4 I/O nodes.

Does anyone have a mirror of the terminals wiki at https://terminals-wiki.org?? It seems to have gone dark over a year ago, and it would be a shame to lose the resource.?
If there is no mirror, does anyone know of a way to contact the owner/maintainer?? I'd like to see if there's anything I can do to help get it back online.
Thanks,
Dave
Working on restoring my very first computer, an Apple II+. Got it mostly
working with just a couple of issues identified at the moment. Some of
the keys on the keyboard don't register but I can work on that. The real
question I have is about the video, it constantly rolls and no amount of
playing with the vertical hold on any monitor I try will completely stop
it. I can get it close but it will slowly roll one way or the other at
best. Tried several different monitors and it is the same on each. Also
tried my old Apple IIe and it seems fine on all the monitors so trying
to decide what might be the issue with the II+. Any ideas or areas to
look?
Thanks.

Folks,
Does anyone have a design for printing card handles for QBUS / UNIBUS
cards? It seems a natural application.
Some grepping of the list logs, a brief plonk through the gadawful
thingiverse search, and various googling have produced no existing
designs.
Thanks,
De
