Well I just picked up a car load of stuff. Manuals, disks and paper tapes, a VT100 terminal and 2 8" floppy drives. I left 4 RL05 drives, 2 racks and card cages behind for another trip. The 2 racks are not quite the same size but I didn't think that they'd tie to the roof of the Toyota. So I'll get a mover to haul the rest. In one of the boxes was what looks like a pair of electric pencils? Anyone in the Ottawa area interested in helping assemble these? How much of this do I need to get the system working, ie. can I put the a card cage and a drive in a smaller rack that will fit in the basement?

old computers

by vcf＠siconic.com

Here's someone with what sound like first revision IBM PCs. Contact him directly. Reply-to: <geo(a)jdm.com> ---------- Forwarded message ---------- Date: Sun, 29 Jul 2001 17:17:36 -0700 From: GEO <geo(a)jdm.com> Reply-To: geomelissa(a)hotmail.com Subject: old computers Hi, A quick question. I am in New York City. I have a couple of early IBM PC's. 64k Motherboard, etc. I can not store these any longer. Is there any one you know who might want them? I also have a bunch of 286 stuff, and some oddball hardware that no one has ever heard of anymore. I have a 5 megabyte syquest removable drive, for example.

Even then, it has to fail a check before they're even going to look at you funny. If not, well, they have a pretty high bar to prove 'unsafe equipment' and they generally don't press it. What use is bringing in a paid witness for $5K when the fine is a few hundred bucks? (Former owner of a 1989 F-150 with a 196o's 460 and a 1984 AMC wagon with a 1970's 360.. Jim, new to the list

OT: HVD SCSI controller

by ken＠seefried.com

Yup...narrow diff is well defined. There's an X-Y matrix of SCSI standards that have X == single ended or differential and Y == [ async narrow (5Mb/s), sync narrow (10Mb/s), sync wide (20Mb/s) ]. Once you get to wide fast, Ultra SCSI (aka SCSI3) and LVD SCSI, et. al., things get a bit odd. My Sun SS20 has a nice wide diff SCSI controller (20Mb/s) with a 4GB Seagate disk. Makes a big difference over the narrow internal drives. Ken Seefried, CISSP

Whats you oldest computer

by rachael_＠gmx.net

I think the oldest I have is a Philips odyssey 2001 build in 1977, not a quiet a computer. I`m not sure about the age of my Regnecentralen RC702 piccolo, sadly its not working, I have checked the PSU, and on a reset the 360kb 5 1/4" starts spining. Does anyone have some infomation about those machines from Regnecentralen. Here in Denmark people seems to have forgotten all about the machines.

"Early" 3.5" diskettes (was: Wired covers VCF east

So try taking the shutter off of a diskette and see whether >that makes the drive happy. Thanks, Fred... I'll have to try it again... The next part of the problem is trying to find such a drive to put on an -11, interfaced in such a way so that I can read/write the diskette. Then I could try loading up an RT-11 monitor and see if we can get the thing to boot.

You sure about that? >From what I understand, every conductor must be capable of carrying a current greater than the breaker that protects it. Otherwise, the cord would be the first thing thing to fail in a overcurrent situation. This would present a very significant fire danger. Even the cheapest kitchen appliances have fairly heavy power cords. It's not because they draw a lot of current or the manufacturers are generous, it's because the fuses / breakers in your kitchen have a higher amperage rating than in other places in the home. So, those appliances must have heavier cords to offer protection.

Circuit protection (was: RE: Latest addition : PDP 11/70)

Instead almost all appliances and devices are required In the UK, the MCB (circuit-breaker) or fuse in the main box is there to protect the ring main (the wiring in the wall). The fuse in the plug is there to protect the power cord. If the appliance needs protecting, it should have its own fuse :-) No fuse can guarantee that the appliance won't burst into flames - the appliance is supposed to have passed some minimal safety testing to make that unlikely - if it needs fuses to pass the test they'll be fitted internally. The remainder of the system does its best to ensure your iring won't burst into flames. Antonio
