Reasonable discussion of the Stabilant stuff in patent #4696832
Hi,
I noticed in another cctech mailing list thread about the NorthStar Horizon
case cover replacements. Recently, I procured a NorthStar Horizon which is
missing its original wooden case cover and I was looking to either buy an
original replacement or make a new one.
I did not get a lot of responses to my queries on other forums for a
replacement wooden case cover so I am considering fabricating my own.
Apparently, it is common for Horizons to have lost their wooden covers over
time for many reasons and others have done what I am considering.
Has anyone built replacement NorthStar Horizon case covers before and would
be willing to build more? They do not look terribly sophisticated to build
provided you have access to a table saw and the proper bits. I was planning
on just copying the dimensions from another Horizon wooden case cover I
already have.
If anyone has a spare NorthStar Horizon wooden case cover, has built new
ones, or knows how to build a replacement, I would certainly like to hear
>from you. Please email me or post here.
Thank you in advance.

Hi folks,
I have a couple pieces of Classic Computer gear I'm off-loading.
(And there is more to come in the following weeks, so keep your eyes open :-)
WHERE THESE ITEMS ARE LOCATED:
San Diego, California, USA.
SHIPPING:
I will not ship, sorry -- local pickup only.
I paid dearly for one of these items (the terminal), so I'm looking
to get back a bit for it (way less than half of what it cost me, and
to have it shipped to me. These terminals are heavy -- on the order
of 35lbs-40lbs.)
---------
Item (1)
---------
Lear Siegler ADM-5 serial terminal WITH original User Manual.
I would like $60.00 for this terminal and original User Manual.
It DOES work! AND, this terminal DOES NOT suffer from the dreaded
screen-rot (a.k.a. mold growing under the protective CRT face plate).
Photos:
(Note: the screen shot of some characters I took is _blurry_ because
of my bad picture taking technique -- the screen produces crisp characters.)

---------
Item (2)
---------
Amiga 1000
-- with keyboard
-- mouse
-- with external 3-1/2 disk drive
No monitor.
Worked last time I hooked it up to a monitor back in 2004. A bit of
yellowing on the casing of all parts, and a bit of grunge (which can
be cleaned, I'd imagine.)
This is a _freebie_ -- no charge.

Contact me OFF-LIST if interested.

Hi,
This week's New Scientist magazine carries a report of a new book called
"Core Memory" by Mark Richards & John Alderman, pub. Chronicle Books,
ISBN 1780811854429. It's a collection of photographs of vintage computer
equiment, inspired by a visit by the author to VCF in 2003.
Anyone seen a copy? Is it worth investing in?
The New Scientist article has a photo of part of the Apollo Guidance
computer, the modules clearly marked "Engineering Prototype".

He didn't state which model sun though...I suspect it would have to be an Enterprise-class or something, since all the smaller ones blow their hot air out on the *sides* not the top.
A SPARCserver 1000 makes an effective hot-air drier (or room heater), let me tell you... but also there you'd have to put anything you want to dry *beside* it; the advantage is that no residual water is going to dribble into it! ;-)

Hi
I will again give a pitch for what I've used. I have a TV that the turret
contact
that were silver plated had warn out, leaving just brass. This was more
than 10 years ago. I tried the tuner cleaners but that would only last less
than a week. I then tried a little DC#4 silicon grease.
To make a long story short, I'm still using that TV today although I only
tend
to watch once a week now. I did watch most every night for some time.
Now if I could only find the intermittent in the vertical drive. I wiggle
things
and it comes right back.

;) there were a lot of design goofs out there.
Actually the worst flub is the external drive setups with power
supplies independent of the main box. I think there may have been
three FDC cards made that suppressed WE/ if the power failed. If
there was a disk in the drive.. wave byebye as it did a motor on,
head load and write "1" to all drives.

Most S100 crates could not pass VDE or a serious hipot attack.
Don't know if the Horizon did or did not as it predated most
of those certifications and likely was grandfathered in like
many. Vibration testing, "ya gotta be kiddin", as there isn't
a card restraint in 99% of the crates.. Some like the pre-B
Altairs flexed so much if lifted by opposing corners the cards
would pop out unless they had a one peice mother board.
