OT: Need some research help -- anyone speak Dutch?

by news＠computercollector.com

Hi, I need to find an email address for Karl de Leeuw, a professor at the University of Utrecht. I tried to explore the university's site but most of it isn't in English. Can anyone help? ----------------------------------------- Evan Koblentz's personal homepage: http://www.snarc.net *** Tell your friends about the (free!)

AmigaEast is cancelled

by news＠computercollector.com

http://www.amiga.org/modules/news/article.php?storyid=4627 Seems that the guy running the show didn't bother to secure his venue funding ahead of time. It was only six grand, and contrary to the comments beneath the story, it was to be held in an airport hotel in Queens, not in "New York City" in the urban Manhattan sense. (Yes I know Queens is part of NYC, I'm from NY; just saying that the people who commented in the thread don't seem to understand the context.) ----------------------------------------- Evan Koblentz's personal homepage: http://www.snarc.net *** Tell your friends about the (free!)

Manuals for Tektronix 4014 terminal

by ggs＠shiresoft.com

Hi, I'm looking for the maintenance manual for the Tektronix 4014 and/or 4014-1 terminals. Bitsavers only has the user manual and I need to fix the terminal. Any pointers? Thanks. -- TTFN - Guy

The PC type Adaptecs had a configurable BIOS overlay like the later SCSI cards and would appear as a "standard" drive. Adaptec also made some controllers that were intended for native support by OS's and hardware designed for ESDI, such as the 3Com 3+Open servers (I used to support a bunch of the 3Com servers).

OT: EMP and Equipment

Vintage Computer Web Site - may not be???

by cmurray＠eagle.ca

It seems I may have jumped the gun here and complimented the site as a 'find' when in fact it may not be that??? Is information blinding us when sober thought produces knowledge and then 'truth' emerges.

The Commodore section has a couple of photos ripped off from Secret Weapons of Commodore, and they don't even link back. One example is the Commodore 232 entry, which even includes the same backplate photo Dan Benson permitted me to use, in the same dimensions I cropped it to, with the same serial number, as well as the rear ports image. -- ---------------------------------- personal: http://www.armory.com/~spectre/ -- Cameron Kaiser, Floodgap Systems Ltd * So.

AIM 65 lives

by mhscc＠canada.com

------------------Original Message: Date: Tue, 03 May 2005 09:03:52 +0100 From: Philip Pemberton <philpem at dsl.pipex.com> Subject: Re: AIM 65 lives <snip> Have you got any other AIM-65 or 6502 appnotes lying around anywhere? I've been trying to track down some of the old Rockwell ANs (IIRC one covered CRT controllers, another one covered DMA) but haven't had much luck. Datasheets are easy to find, but ANs seem to be the equivalent of gold dust :-/ Thanks, -- Phil. -------------------Reply: Phil, I have about a dozen, but not the two you're looking for. One day Real Soon Now I'll scan & send them to Rich Cini for inclusion in his most excellent AIM65 Web site section; I started to scan them but wasn't happy with the fine print detail. Meanwhile, I'll send you a list of what I've got, off-list. mike

Antenna and #6 CU ground lead were reduced to little BBs or otherwise vaporized. The affected systems were one floor down. Not less than two portable (battery only) radios had the RF stages fried. The term EMP is ElectroMagnetic Pulse refers to any large magnetic pulse. It is not exclusive to a nuke going off though that can generate a whale of a big one. Though dumping a sufficiently large (say 100KW/S) stored charge into a coil can really mess up local equipment. Years of working around commercial towers I've seen what those big sparks from the sky can do. Its impressive. Allison
