Caig ProGold / Stabilant 22

by aek＠bitsavers.org

The wisdom of using this stuff was being discussed on another mailing list, so I thought I'd see what people knew about it. I suspect it is similar to this: http://www.stabilant.com/techt20h.htm There seems to be almost nothing on the web about what the Caig stuff actually is. Materials safety data sheet lists ingredients as 'trade secret' Reasonable discussion of the Stabilant stuff in patent #4696832

NorthStar Horizon Case Cover Replacements

by lynchaj＠yahoo.com

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. Andrew Lynch

2 pieces of Classic gear available in San Diego, California

by elf＠ucsd.edu

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.) http://home.san.rr.com/instep/gear/Lear-Siegler-ADM5 --------- 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. Photos: http://home.san.rr.com/instep/gear/Amiga-1000/ Contact me OFF-LIST if interested. --ef

Computer porn book.... :-)

by stanb＠dial.pipex.com

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". -- Cheers, Stan Barr stanb at dial.pipex.com The future was never like this!

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.

Another reason to shield >things. ;) 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 "PC" boxes from the 1970's had some sort of basic design >problem; EMI radition being only one of them (Did the Horizon pass >VDE certification?).

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. Allison > >Cheers, >Chuck > >
