>DON'T EVER GO INSIDE A RUNNING OR RECENTLY POWERED OFF >MONITOR OR TV WITH A CRT UNLESS YOU KNOW WHAT YOU'RE DOING. Just how recently would recently be? That, frankly, is a matter of dispute. The *correct* answer is to know how to discharge the anode voltage, have the appropriate tools to do so and to measure the result to confirm success, and to perform the procedures properly. (Hint: If you don't know how, find somebody who does.) The service manual from whatever CRT-based device you're messing with should have proper instructions. And if you don't have the service manual, what in heck are you doing in there anyway? Thanks, Tom Applefritter www.applefritter.com

> > I think I managed to hit 100+MPH on a few occasions. > > > > WHEEEEEEE!! > > I thought all Americans drove at no more than the 50? limit ;-) Speed limit on most U.S. Interstate highways is 65mph... urban areas typically mandate a lower speed limit, we have a section of Interstate locally known as Dead Man's Curve that mandates a 35mph speed limit for semi tractor-trailer rigs, and another section called Hospital Curve where the limit is 50mph for both trucks and cars (and I won't even get into describing our local section known as Spaghetti Junction). Montana? and/or North Dakota flirted with no limits outside ruban areas (actually the law specified that speeds must be reasonable and prudent for the conditions or something like that), but they maye have finally done away with that due to lobbying by insurance company interests. -dq

Switching RS-423 connections?

by cmcmanis＠mcmanis.com

Hello everyone, I would like to build a "4:1" box that can switch between one of four DEC MMJ consoles. This is so my mini-cluster can have one terminal be the console for four machines. However, I've noticed that sometimes I get a 'break' sent if I simply unplug and plug, so to prevent that I want to make a "hold" circuit such that the VAX will continue to thing a terminal is attached. Any suggestions? --Chuck

RL02 question

by xds_sigma7＠hotmail.com

DC = normal data cartridge, whereas I believe the EF = error free. What do you mean by set? If you mean that its turned red, then I would be less than enthusiastic about using them, and if I bought them on Ebay or something, I'd want my money back.

Trash or Treasure?

by mcguire＠neurotica.com

Sounds like a control computer for a GenRad automated pc-board testing system. They used various pdp11 machines to run their board testing machines. I'd say it's a pretty nice score. -Dave McGuire On September 22, Joe wrote: > A couple of weeks ago I found a box in a scrap yard with a half height 8" > floppy drive it in.
