I have the following tubes (multiples of each). Looking for offers,
shipping from 61853. Please contact me off list.
There may be a few typos in here. I also have a variety of Z80 series chips
and maybe some Z8.
Thanks, Paul

Hi, all, I'm looking for any/alldocumentation for the PDP-11/34A cache, the
KK11-A. (And no, it's not in the 11/34A print set!)
At least one document does exist, the KK11-A Cache Memory Technical Manual
(EK-KK11A-TM-001); this page references it:
http://www.pdp-11.nl/pdp11-34a/cpu/options/cache-info.html
but I can't find it online (well, someone's Flickr site has an image of one
page of it, but that's all).
The mention there of "cut the 'cache hit line' on the DD11-PK backplane" on
that web page (above) has me concerned! But in general I'd like to know more
about this board.

I've fixed a couple of keyboards using hobby shop track bed foam, but have
not been very happy with the "feel". That foam is considerably less
resilient than the material Keytronics used. After trying a number of
alternate materials, I have found something that is almost identical to
the original. Take a look at eBay #171549720453 for an example.
It's 5mm thick with an adhesive backing, sold for shoe inserts. I stuck
0.075" plastic sheet to the backing, then turned it over and used spray
adhesive for the aluminized mylar. Worked like a charm. Just finished
resurrecting a N* Advantage and the typing feel is (in my opinion) far
better than the last unit I did with track-bed foam (Corvus Concept).

Hi guys,
sometimes in the past I've reapired some OPUS 220 Terminals from
Esprit Systems Inc, Melville NY for an other company.
(I still have one left over that still works and I want to keep it for
my 11/83)
>From that time I still have new 3 Flyback Transformers here,
and now I have to repair another Terminal (some Siemens Device) where the
original FBT is sold out everywhere.
I'm now searching for the display schematic part with the FBT from the Opus
220 Terminal to look if I could transplant one from the new FBTs to the
Siemens Monitor.
Sure, I could do some reverse engeneering in the Opus Terminal but
hopefully one has what I need already?
Thanks in advance,
Holm

Hi all --
Subject line covers the basics; I have a nice looking Xylogics 472 but
someone has stolen the EPROM from it; anyone
a) Know what size EPROM goes in this socket (24-pin)
and/or
b) Have an image of its contents
So that I might replace it?
Thanks as always,
Josh
Hello all,
I have a Mac portable that refuses to even attempt to boot.
I get random junk on the screen that is different on every power up, no drive activity and no sound.
I am thinking the onboard surface mount electrolytics are due for replacement.
I was able to read the values off of most of the caps but I was not able to read the follow caps. C4, C5, C15 and C24.
Does anyone know what value those caps are?
Thanks,
Matt

This is rather off-topic, although I will be using said chassis punches for classic computer restoration
I am thinking of buying some chassis punches, in particular some of the ones for D connectors (and others).
One brand I can easily get in the UK is Greenlee. Am I right that that is a respected manufacturer of them?
Not cheap, but then I can't afford the cheap ones.
Also Greenlee do an accesory called the Quick-Draw or something, a handheld hydraulic device that fits
on said punches. It is darn expensive, but I want to know what advantages it gives. If it is just faster then I
am not interested. If it means I can cut thicker metal then I might be.

Back in 2007 Stan Barr posted a comment about a book that was pure computer
geek porn: "Core Memory" by Mark Richards & John Alderman. I thought it
would be a good stocking stuffer for myself from someone in the family. I
went looking on Amazon for it. The price is $172 for a new hardcover and
$78 for a used hardcover.
This is ridiculous. I thought it was only school books that were at totally
unreasonable prices.
Now, I can get the nook electronic version for $13.99 but this is a *coffee
table book*, something to be displayed. It's geek porn.
So then I went and looked at some other books that are niche. I enjoy
analog design and a Jim Williams book is always good. "The Art and Science
of Analog Design" which is about 15 years old is $50 in paperback.
I guess the printed page is dead. Gutenberg RIP.
Hello group
I'm toying with the idea of writing a simple word processing package along
the lines of Wordstar for my Retrochallenge 2015/01 entry.
I have used many word processing packages over the years on many machines
>from 8-bit machines to mainframes. Within the following bounds I'd love to
know the packages that have been the favourite of list members over the
years and why.
If I implement this I'd be looking to keep within the following bounds:
* text only - ideally support VT terminal 80x24 or 132x24/36/48 or DOS
80x25 display size.
* two printer drivers - text only and Epson LQ (or possibly IBM Proprinter)
* support small range of printer specific fonts
* support proportional text
So a little more than a text-editor but only enough to support simple
formatting and styles (bold, italic, underline for example).
Ideally I'd like to implement a clean, logical design without many 'bells
and whistles' concentrating on the core functionality.
Kind regards, Mark.
