There are lots of types of Loctite, though, and the one for polythene and nylon isn't the same as the one for polyurethane.

TRS-80 Mod I Video Display

by classiccmp＠vintage-computer.com

I've got a TRS-80 Mod 1 with a bad display. There is a horizontal scan line in the center of the screen but no vertical sweep. Is anyone familiar enough with these displays to give me repair hints? Failing that, does anyone have a working one lying around that they'd part with? Thanks! Erik Klein www.vintage-computer.com/vcforum The Vintage Computer Forum

OT-- need plans for a wireless switch

>disconnect the horn and use its button Make sure you put a switch to toggle between horn and ham radio. I don't know about other states, but you can't pass vehicle inspections in NJ without a working horn. -chris <http://www.mythtech.net>

I've used both products. In my previous life, I was an industrial control contractor in food packaging plants. We used the Loctite stuff. to stick polyurethane conveyor belts together as in a spliced loop. These belts ran at 2-300 ft per minute in a wet, oily, washdown environment (salad oil bottling plant) for months without a break. It was extremely expensive and the supply room checked it out and in. The clerk used to chase me down when I forgot to return the splice kit. The "cyanopoxy" stuff was used to build up delrin and teflon conveyor gudes when they wore through, until new ones could be machined out of block stock. I know it would stick a teflon gear together and would probably be stronger than the original gear. Just be careful and don't stick your fingers to the gear. You will have to remove the skin with a single edge razor blade...don't ask, trust me on this one. I can't remember how much it costs, but I'm sure it wasn't cheap.

Can anyone id these HP ICs?

by swperk＠earthlink.net

Hi Joe, The only reason that I can come up with for HP's construction techniques is that their IC's were made during the heyday of HP's own IC division. They overbuilt everything, probably because of reliability concerns. Other people certainly will know more about this than I do, but I think that HP was one of the earliest developers/fabricators of ECL. Thanks in advance for the manual! Regards, Stan Hi Stan, Thanks for the info. Any idea whey the fancy construction? I've dealt with ECL before but never seen anything like this. BTW I'm made copies of that memory board manual for you. It's packed and ready to ship. I'll try to drop it off at the post office today.
