Free in DC area: Fuji SMD drives

The drives have been "self-dismantling" over the past couple of decades. In particular, the glue that holds the optical gratings has - in every case that I've seen - come undone. I've managed to make a few good PerSci's by combining parts from broken ones, at least. But they're amazingly complicated drives. (As well they should be, considering how much they cost back in the 70's - you could buy a brand new car for what 4 PerSci's cost.) Even on the broken ones there's a huge assortment of electromechanical parts still in place. How many other 8" floppy drives had motorized loading/ejecting? (I know that some Shugarts and NEC's had the option of ejecting via a solenoid, but I'm not counting solenoids here. And I'm certainly not counting the drives that would, if you loaded and unloaded the head often enough, vibrate so much that the door popped open! ) Tim.

A few new finds

by jrkeys＠concentric.net

Picked up a Wavetek waveform generator model 159 yesterday at the thrift and it works great ($3.95). also picked 6 really nice mousepads for that part of the collection at the same thrift. Picked up some in the box 2600, Genesis, and Odyssey game cartridges from 80 cents to $2.99 each. I know they are not 10 years old yet but has anyone else notice the number of playstation one's at the thrift's lately ? They have been priced from 3.99 (console only) to 14.99 (complete systems). New games (unopened) have been $1 to $13 dollars at the thrift's here.

New finds

by dlw＠trailingedge.com

It's been a good day. Picked up a couple of new items. One, I picked up an Atari Portfolio with spare 128k and 64k memory cards and the PC Card drive from someone in Germany in exchange for some DVDs I produce. It near mint condition it appears. Doc is in german but I can understand enough to get me through. Now to go hack some ATMs. :-) The other cool item was the first dual processor BeBox! First in this case as in the first one off the assembly line. Can't wait to get this home and hooked up. Of course I don't think that falls under the 10 year rule. ----- "What is, is what?"

Pocket protectors Was: RE: Fun "events" for VCF

Clip the pocket protector on with alligator clips attached to red and black wires... this will have the advantage or providing one with an emergency supply of spare test leads. :-) > > This just got me to thinking.... > > How did pocket protectors become associated with 'computer > >enthusiasts'? Ok, I see it's time for the Pocket Protectors 101 course... Since I wore one back in college during a time when I was taking a lot of math, science and electronics classes, I'll take a guess at answering this. Back then, math, engineering, electronics, etc. students were the most likely students to be computer hackers. Such students have a need to carry a wide variety of pencils and pens, etc. in their shirt pockets; for example, I typically had fine and extra fine point Scripto (?) "click" pencils (press on the little chrome tab that holds the eraser and more lead comes out), a retractable erasor, a couple of different pens and perhaps a felt-tipped marker or two. Pocket protectors are made of reasonably thick vinyl and lessen the chance of one damaging oneself, or one's clothes, if one fall, bends, or bumps into something the wrong way --- that is, in such a way as to get stabbed by the writing instruments in one's shirt pocket. Pocket protectors also keep one's pocket from getting dirty from lead and pens that might leak ink; in addition, they protect the shirt pocket >from the wear of clipping and unclipping writing instruments to and >from it. > > And how many here have wore a pocket protector on a regular > >basis in the past? > > What the hell is a pocket protector? You've never heard of a pocket protector before? Amazing. Perhaps it's a language translation thing, and they're called something else in your country. Over here, they're very popular. A pocket protector, as mentioned above, is a reasonably heavy vinyl lining for a shirt pocket, into which one places writing instruments, etc. Refer to figure 1 below for an illustration of a pocket protector. The pocket protector is represented by the asterisks; the straight lines represent the shirt and pocket. | |* |* |* *** |* *|* |* *|* |* *| |***| +---+ fig. 1 ASCII cutaway representation of a pocket protector. -- Copyright (C) 2001 R.

Ethernet -- thicknet and thinnet before 10BaseT

Coax. How dumb can it get. I'm not quite sure what you're saying. If you're saying that the earliest bridges were dumb repeaters, you're wrong. The definition of a bridge is a layer 2 device that passes traffic according to the destination addresses contained in the packets. If you're saying that the way a bridge works is to learn where addresses are, and until it knows, it will pass packets everywhere, that's true. Even with old bridges, you wouldn't be able to see *all* the network traffic because the bridges would split the net into different collision domains (that's what they are for), so the only traffic that would go everywhere was broadcast traffic. You wouldn't even see all the broadcast traffic if you had a router or two in the system, and there's nothing new about that either. -- Pete Peter Turnbull Network Manager University of York

OT? news clip

by fmc＠reanimators.org

Saw this tidbit in the latest (July 2001) IEEE History Center newsletter, and thought the scanning electron microscopy folks here might find it interesting: 2001-2002 IEEE Life Members Fellowship in Electrical and Computing History This year's Fellowship in Electrical and Computing History has been awarded to Cyrus Mody, whose research is on "Scanning Probe Microscopy: The Genesis and Development of Tools and Practices in Engineering Science, 1970-2000." Cyrus Mody earned his A.B. in engineering science from Harvard University and is pursuing graduate studies at Cornell University.
