monitor with screwed colour in bottom-right of screen

If physically unplugging the degaussing coil (which is the loop of wire around the front of the monitor) fixes the color issue I would suspect that the degaussing switch circuit has become leaky and is leaving the coil partially energized all the time. The coil sees power for a short period when the monitor is first powered up or the user calls for a 'degaussing' >from the monitor controls. Under normal use the coil should not be energized. -Neil

monitor with screwed colour in bottom-right of screen

>It broke >free of its moorings whilst going round a sharp corner - one very heavy >monitor somersaulted across the boot of the car with one hell of a bang >:-( > >I'm amazed the tube didn't implode to be honest, I don't know, I've found monitor tubes to be fairly sturdy when it comes to imploding. I've TRIED to break them before when throwing them out (why? because its fun). And it usually takes a few good whacks with something fairly heavy to crack the front glass. And then it just hisses as the vacuum is broken and lots of nasty dust floats around... no magic imploding like you see on TV. On the other hand, I've found the back end of tubes, to be very sensitive to breakage, and have cracked the gun off a number of them due to improper shipping, or just giving a hard throw into a dumpster. But again, no imploding, just broken glass. I do plan to attempt to play "monitor golf" with the next one I throw out... take a 10 lb sledge hammer, and swing it like a golf club at the front of the monitor, and see either how far you drive the hammer into the screen, or how far the monitor rolls away. :-) And alas, the building I work in is being sold to a more conservative owner (the local hospital), so I'm loosing my ability to toss things off the roof to watch them smash into the parking lot. The current owner lives many states away and is a little more relaxed about these things... but I don't think the hospital will be happy to have me continue my adventures under their ownership. :-( -chris <http://www.mythtech.net>

[x-post from port-vax] HSD05 formatting

by port-vax＠microvax.org

Hi again guys :) I've got myself a storageworks shelf (with floor-stand hardware and the smoked doors :D ) that has 3 SBBs and a HSD05 DSSI<->SCSI unit. It's hooked up to my 4000/200 with a KFQSA MSCP DSSI card, and i've set it up so that I can SET HOST/DUP/UQSSP/DISK 0 into the HSD05 and run all the setup utils and toys there. However, I don't know how to partition these disks under NetBSD - i've had a bit of a fiddle with disklabel but quite frankly I get a bit lost, and most of the time disklabel locks up on me anyway - I suspect this is because it cannot know the true geometry of the disk it is talking to, but that's just a supposition... The three disks I have appear to the VAX firmware as DIS610, DUA620 and DUA630 - all appearing as RF72 disks, and the VAX is netbooting NetBSD 1.5.2. Can anyone explain to me how I can get these babies formatted so I can eventually install NetBSD on them? TIA alex/melt

"RP02-like" disk packs; yours for the postage

by brad＠heeltoe.com

Hi, I bought 3 "RL02-like" disk packs on ebay which of course turn out not to be RL02's. (the picture was of an actual RL02, so I took a chance...) Anyway, before I toss them in the dumpster if anyone would like them they are yours for the postage. They are physically ok and fit into an RL02 drive. They spin up fine but don't come ready (no doubt due to missing timing track or something like that) Perhaps some other non-DEC machine can use them. -brad

TRS 80 Model 1 Question

by majordomo1＠cox.net

Ahoy, I've performed a cleaning procedure many times using a paper clip hooked under the key, and pulling straight up till it flew out. One drop of alcohol of at least 91% is then applied.

VaxStation Keyboard Insanity

by jeff.kaneko＠juno.com

Yes, S3 is in the DOWN position, to use the framebuffer. The VaxStation completely ignores the LK201 that I've plugged into it. All four lites on the LK stay ON.
