I am forwarding this interesting bit of news from the PDP-8 newsgroup
that John has to say.

What he said. :)

That's what I'd really like to do, but I can't afford one right
now... :-(

Hey, no fair, I GOT the darned thing from you! ;)

Ahh, thanks for the offer, but I've gotta keep this one. :-)

I only have the transistors and the micros ones. I do find the latter
quite useful, as I can often look up the pinouts somewhere else, or
sometimes I just want to know what type of device some chip is.

They were either 99p or 199p each from CPC. IIRC they were on one of their
special offer sheets that they send out to account customers every weekend,
about 18 monthsor a couple of years ago. Probably a one-off special as I
don't see them in the catalogue :-(
The transistor one is about 5/8" thick, 8.3" wide x 5.8" high, and it says
"'97 The Transistor Manual" on the front in Eglish, and something in
Japanese underneath. On the back it has two barcodes (one EAN, the other
JAN?) 978478983614 and 1923055013001, and "ISBN 4-7898-4361-0 C3055
Y1300E" (the 'Y' is actually a Yen symbol, but in deference to the
ISO-8859-impaired I've approximated :-))
The other two are obviously part of the same set.

York isn't blessed with many of the right sort of bookshop, but that seems
like a good way to get them. Mine are pretty old, around 1980.

The cathode in the CRT used in the 4000A loses its emission ability over
time. There's nothing you can do about it. The usual techniques for tube
rejuvenation don't seem to work.
The later 4000B monitors use a different tube which doesn't seem to suffer
in the same way.

Got some misc stuff I don't want.
A few boards pulled from an old PBX:
One marked `LC 96B V 1' and `SYSTEM CONTROL', one marked `LC 78B V 1' &
`PROCESSOR' (AMD 8080A CPU!) & one marked `LC 95C V 4' & `MEMORY 1' (two
banks of 9x uhhhh 1484?, one bank of 8 wide ceramic 24 pin DIPs). The dang
thing weighed a ton, so I couldn't get the whole chassis, but I pulled the
more interesting cards.
One Sperry PC 384KB memory upgrade, new in box, (handwritten) serial #
47y791.
Yours for shipping from zip 43211, or it goes to the trash.
ja ne!

I believe that there *is* a pot inside that can brighten the monitor,
but I also believe that this is a common and well-known (at least on
the NeXT news groups) problem with the original monitors: they
eventually get very dim--more or less too dim to use. This happens, I
seem to remember, after only about 5,000 hours or so. It is a function
of the phosphor, it is not prevented by dimming the monitor, and it was
rectified in later versions of the monitor. (The details behind all of
that information escape me. I suspect you could post a request at
comp.sys.next.hardware, and you'd get a reply from someone who knows it
all right off the top of his or her head.)
Good luck!

Hi,
Seen on another list...
The HP 3000/922 is a PA-RISC system, running MPE/iX. It isn't supported
by the PuffinGroup port of Linux. Just the computer is about the size
of a 2-drawer file cabinet.

Since there are a few people into the NeXT machines on here,
I wanted to offer this here. I've got an extra N4000A monochrome
monitor that I wish to get rid of...and it's FREE! The only problem
with it is that it is dim. Otherwise it works great. I've got
another N4000A and a N4001, so don't need this additional monitor.
Drop me a line if interested. It's just outside of Washington D.C.
I'd hate to just dispose of it if nobody wants it but I don't have
room enough for all the machines I want, much less extra monitors for
all of them.
