Evil VAXstation 3100 disk mounting gaskets!

by sethm＠loomcom.com

Hey all, I've got a question for DECheads out there who are familiar with the VAXstation 3100 (and DECstation 3100, for that matter) series of DEC systems. These little beasts don't use mounting brackets like the rest of the desktop computer universe. They instead rely on the little screw holes located on the bottom of standard 3.5" form factor harddrives, and these really INSIDIOUS LITTLE RUBBERIZED GASKETS that you wedge into various mount-holes on a metal plate inside the VAXstation's case. The drive sits on these gaskets, you see, and gets insulated from the scary conductive metal plate, while still getting a little airflow under the electronics. I'm ALWAYS missing at _least_ one gasket whenever I want to mount a drive. Often, I'm missing all four of them at once, making life terribly difficult. I've resorted to using non-conductive washers and screws with _really_ big heads to kind of work around it, but it's a sub-optimal solution. Does anyone know where to get these little guys? Did DEC have a part number for them? Or are they a common part available at your local Fry's Electronics, and I just haven't found them yet? I really need some, you see. Thanks for any (and all) help! -Seth -- "As a general rule, the man in the habit of murdering | Seth Morabito bookbinders, though he performs a distinct service | sethm(a)loomcom.com to society, only wastes his own time and takes no | personal advantage." -- Kenneth Grahame (1898) | Perth ==> *

Does the Balls-O-Meter wear out? :) As tank-like as the Selectrics are, you really _can_ wear them out. My mother used to make her living typing court transcripts (in the evenings, from the tapes the court reporters make during the day). One time, she took her IBM Selectric II to a new shop for minor repair and adjustment. The shop owner commented that he'd never seen wear on certain parts until then. When the job was done, he asked her to try it out in the store. About a minute into the machine-gun reverie, he commented that the two of them were going to become fast friends. He was right. She took one of her two machines to the shop at least once or twice per year. I don't know how fast she typed, but it was well in excess of 100 wpm. 14.8 cps - it's not the law, just a good idea. -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

Persistence of Vision (was Re: Cool hack (was Busses vs no busses ))

by RCini＠congressfinancial.com

Well, it must have been a brain fart. I can't find the article at all. Not in PE, EN, CirCellar, or N&V. I have no idea where I saw it. I did come across a project for the BS1 in "Programming and Customizing the Basic Stamp Computer" by Scott Edwards (p. 87) for a POV message machine. It wouldn't be too hard to add a Dallas serial clock and change the code to make a clock. Rich -----Original Message----- There was a project just for this in Electronics Now or Popular Electronics just recently. I'd say Feb. or March issue. If I have time tonight, I'll dig-up the article. As I recall, it uses a PIC and a group of LEDs on a pendulum to provide the date and time using the same "persistence of vision" as mentioned below. I don't recall if the swinging was user-invoked, motorized or magnetic. Rich ========================== Richard A.

I can't recall either, but that brings to mind an interesting project a friend of mine worked on quite a few years ago. The Art Museum here was having some kind of show and an artist wanted to paint electronic pictures. My friend designed the electronics (I built the circuit boards) to put a line of LEDs on a pendulum and paint pictures electronically as the pendulum swung through its arc. With the multi-colored and higher intensity LEDs available today, it would be really cool to do the same thing but with color pictures. Doesn't sound like too hard a project especially with the speed of todays computers. ========================== Richard A.

Rogue for VAX...

IMHO still the sweetest laptop keyboard ever. BTW, it must have been "heavy duty" as it's still working just fine. (I have a pretty light touch for typing...)
