[CCTALK] [CCTECH] scanners & circuit boards...

>> There's a guy here who had one of those auto-glass repair places buff >> a bad scrape off his 21" Nokia. Yes, the tube, not the bezel. >> Personally, I think the person who did the work is certifiably (a) >> stupid (b) suicidal - take your pick. But they did a great job. > >If the damage wasn't very deep, I'd not be too worried about it. The >thickest part of a glass tube is the face, which could be anywhere from >1/4" to 1" thick. I don't know what kind of buffing equipment the guy used, but if it is like the stuff I have seen used to take scratches out of our fire trucks... I wouldn't be too worried about buffing a tube. The last one I TRIED to break, took a good dozen swings with the frame of a heavy rolling chair before it cracked... and even then, it just cracked. It took a few more hits before it actually gave out and collapsed. Next time I will whack one with a sledge hammer and see how many hits it takes to get to the center. (I am still a little leary to toss a monitor off the top of my office building... I'm afraid I'll damage the asphalt... the landlord would kick my ass if I did that. But it is only 2 stories so I am thinking about it... I don't think a 14" monitor could build up enough energy to damage the parking lot on a 30 foot drop... I just haven't gotten the guts up to try it and find out) -chris <http://www.mythtech.net>

[CCTALK] [CCTECH] scanners & circuit boards...

by Robert_Feldman＠jdedwards.com

Toothpaste is actually a good fine abrasive. I have heard it recommended before (for polishing scratches from the display panel of a Radio Shack Model 100). Another product is called "Mirror Glaze." The exhibit staff at the museum I worked at used it to buff small scratches from Plexiglas display cases. -----Original Message----- From: Tothwolf [mailto:tothwolf@concentric.net] Sent: Thursday, May 16, 2002 1:49 PM To: 'cctalk(a)classiccmp.org' Subject: RE: [CCTALK] [CCTECH] scanners & circuit boards... <snip> I've buffed out tiny scratches in the past with (of all things) toothpaste, but for the more visible but still minor scratches, I need to find something else. -Toth

[CCTALK] [CCTECH] scanners & circuit boards...

by Lee.Davison＠merlincommunications.com

I'd be more concerned with accidentally scratching the glass bed of the scanner due to sharp component leads. You can't scratch glass with metal. What you can do is leave a thin trace of metal on the glass. Gewelers rouge will easily remove this is nothing else will. I guess that there is a slight possibility of degrading the contents of an EPROM if its window isn'tcovered. Glass is opaque to UV so you won't erase EPROMs either.

Try running your windshield wipers without the rubber. Although, it may be true that glass has a hardness greater than most metals, this doesn't mean it won't get scratched. The problem is that it also fractures easily ( sometimes at a microscopic level ). The tiny chips embed in the metal surface and that scratches the glass. This is a multiplying effect. Also, most oxides of metal are harder than glass. And lastly, the quartz windows of the EPROMs are harder than glass. >>> >>> I guess that there is a slight possibility of degrading the >>> contents of an EPROM if its window isn'tcovered. >> >> Glass is opaque to UV so you won't erase EPROMs either. > >EPROMs don't have UV-opaque glass windows, they have >UV-transparent quartz windows.

[CCTALK] Annex Term Servers

by pat＠purdueriots.com

I've got an Encore Annex (first model), and Encore Annex Two sitting here that I'm wanting either to get rid of. If I don't get any 'bites', I'll probably pull the usefull chips and can the rest. I'm also going to the Dayton Hamvention thingee on Saturday. If anyone wants to meet me there to get one of these, let me know. If I don't here a reply by Saturday night, they'll probably end up in pieces. They both appear to work (I have no software for them...) the lights light up and the annex one (which has DE9P's so I can hook up a serial console easily) does its diagnostics ok. -- Pat

[CCTALK] Subject preface

by mythtech＠mac.com

I know Jay said he isn't going to touch this until the new server settles down and the kinks are worked out... and that is fine... but I figured I would mention it as a mental note for when he can get the chance to look into things. BAD side effect to the subject preface... sorting by subject no longer works properly (at least not here, Claris Emailer 2.0v3, but I suspect others as well). Based on where the responding person's email client sticks the Re:, and based on if it has double prefaces, the subject will be sorted in different places. As a result, yesterday and today's posts have been listing all out of order. That makes it much harder to follow a thread, and near impossible to delete a topic in bulk that doesn't interest you. So just food for thought, and my vote to remove the subject preface entirely (at least the list server inserted one... manually inserting OT or WTB, or FS or whatever for certain postings isn't really a problem) Of course, this should really go private to Jay, but I can't find his addy right now (I am sure I will spot it right after sending this) -chris <http://www.mythtech.net>

[CCTALK] In a bind-need ROMs for IBM laser printer

by RCini＠congressfinancial.com

Hello, all: I'm in a bit of a bind. I need a set of ROMs for the IBM 4019-E01 laser printer. I need to uninstall the PostScript option, which requires reinstalling 4 ROMs. Lexmark parts carries the U25/U26 ROMs but not the U27/U28 ROMs, so I would have to order a new controller board for lots of $$$. If someone has this printer and can copy these ROMs for me, I'd greatly appreciate it. Alternatively, I'd take a controller board from a non-working 4019. Please contact me off-list. Thanks. Rich ========================== Richard A. Cini, Jr. Congress Financial Corporation 1133 Avenue of the Americas 30th Floor New York, NY 10036 (212) 545-4402 (212) 840-6259 (facsimile)

[CCTALK] First SGI Workstations?

by aek＠spies.com

> I am wondering what the first SGI workstation was There should be an SGI hardware FAQ that I contributed some info to on the web that shows the early products. The first Unix products were based on the SUN 68000 design and ran a swapping Unix (1400 series) Later 2000 and 3000 series Irises ran with paging and 68010'a and 020's The 68000 based machines did not have a directly addressable frame buffer, and the original IRIS display didn't really do bitblts very well, making it great for visualization, but pretty poor as a windowing workstation. There were a few diskless products that could be netbooted and used as terminals in the 1000 series, but I'm not sure what software they ran (I suspect it was some variant of the Stanford V kernel)
