Have you grown tired of your WiF232 Internet Modem?

I would like to get a WiFi232. It appears a new production "batch" may not be forthcoming. If the new has worn off yours, please let me know. Fair price or maybe a trade. Thanks, Jim

Would analog computers have be used in control systems where feed back would be use. I can't quite recall those classes anymore (I haven't needed them since the early 80's). Also my Calculus professor gave us an example of Calc used daily. I can't quite recall all of it but something like Acceleration Speed force I think that you can derive the next from the later. I'm sure there are other examples of where we actually use these formulas without realizing it. -- Linux Home Automation Neil Cherry ncherry(a)linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies

replacing NeXT battery
by william degnan 04 Dec '17

04 Dec '17

Here's a good thread about rebuilding the NeXT after replacing a dead battery http://www.nextcomputers.org/forums/viewtopic.php?t=3475&sid=9630ef34e48339… I am looking also to see if one has a *working* battery how to back up the configuration to diskette or the network or something before the battery dies so one can resume without a big thing to rebuild the machine config, trying to guess everything I did to get it just right.

Bernie S at Festivus 2017

>> Bernie S of 2600 magazine fame...[has some wire recordings to >> retrieve from the Radio museum and will stop by Festivus] >> Wire recording predated magnetic tape, and was used by the 1950 SEAC >> computer for data storage. Early microprocessor computers, and some later video-gaming home computers, used audio data cassettes for data storage. We in this list know this. But recent experience I've had with 21st century young adults, is that such use is a complete surprise to them. and, a lot of modern computerists, work far harder than necessary, to digitally extract data from those old audio recordings. So, it's a surprise to me, that the earliest wire-recorders, were also used with some computers of the 1950's. If he has more information on that use, I suggest that VCFed try to obtain some information from Bernie "S" - does he have a last name or is his identity confidential for some reason? - and make that information available and archived.

Bernie S at Festivus 2017
by Jeffrey Brace 04 Dec '17

04 Dec '17

Bernie S of 2600 magazine fame will be attending Festivus. He said: "Btw, Saturday I'll be stopping by the Radio Technology Museum to retrieve some restored wire recordings from the 1940's that my late father made. Wire recording predated magnetic tape, and was used by the 1950 SEAC computer for data storage. https://en.wikipedia.org/wiki/SEAC_%28computer%29 <https://en.wikipedia.org/wiki/SEAC_(computer)>" <https://en.wikipedia.org/wiki/SEAC_(computer)>If anyone is interested in seeing this 1940's wire recording technology demonstrated on Saturday, then let Evan or myself know. Bernie would be happy to demonstrate it at the Antique Radio Technology Museum. -- Jeff Brace

Museum letter to Festivus Claus
by Evan Koblentz 04 Dec '17

04 Dec '17

Dear Festivus Claus, Here are some things we would really like to have for the museum. We've been very good this year!!! - A long RCA cable (about 20 ft.) so we can attach the Lego demo station (Laser 128) to the big workbench monitor. - Demodulator (to attach a 2600 to RCA input on the same big monitor) - Combined DVD/VCR unit, that would save space vs. separate ones. - Fanless rack-mount switch. Martin recommended fanless versions of the Juniper EX2200 or Cisco 3010. We'd like at least 12 ports, 24 would be ideal, with PoE support. - Rack-mountable UPS with good batteries - Dark chocolate for Evan (thought I'd sneak that in!) - Rack-mountable sliding keyboard tray - Keyboard with built-in trackpad/trackball - Two matching office chairs -- black/chrome, cushioned, wheels, arm supports - One bench-height stool -- black/chrome, cushioned, wheels Perhaps some of next week's party attendees can bring us any of these items on behalf of Festivus Claus. Keep in mind it's all tax-deductible.

Museum report
by Evan Koblentz 04 Dec '17

04 Dec '17

Adam and I were at the museum from 11:00-6:30 today. - Jason H., who used to live out here and was an active MARCH member, visited today from Seattle. He hadn't seen the museum. The first words out of his mouth upon entering were, "It looks professional!" vs. our old exhibit. He hung out with us until about 5:00 and even helped clean our workbench. - Adam counted our Commodore 128s .... FIFTEEN! That's a dozen more than we need. We'll test them all another time (probably at the next workshop in January) and then figure out how to get the surplus into collectors' hands. - Adam also sorted/organized some other Commodore accessories, joysticks, etc. which were cluttering our warehouse entrance area. - We checked out a donation of a TI Professional Computer (Osborne-esque) which arrived yesterday. It looks brand new except for the keycaps, most of which are yellowed although a few random ones seem pristine. Weird! - We put aside 50-something Pickett slide rules and a new-in-box Atari Flashback 2, which as Jeff B. posted will be given away at Festivus. - We put another Flashback 2 into the museum workshop and attached it to the big monitor on the wall. It works fine but there was no audio. We determined the wires from the monitor's side-mounted speakers were damaged. Chances are high that some of the more experienced members can fix this. I'd still rather connect one of our real 2600s, but first we need to acquire a modular (not a demodulator) because the monitor doesn't have a coax input. I think Dean said he has one. - We had a slow but steady stream of museum visitors. Maybe about 20 people total. Lots of parents/children due to the InfoAge holiday train show. The highlight was a precocious and extroverted 7-year-old girl who really got into it. - We stopped at Home Depot and got a 50-pack of contractor-grade trash bags. Our warehouse supply of these was done. ________________________________ Evan Koblentz, director Vintage Computer Federation a 501(c)(3) educational non-profit evan(a)vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation instagram.com/vcfederation

NeXTstation

NeXTstation in the museum wouldn't turn on today. No idea why! This needs some TLC at the next workshop. ________________________________ Evan Koblentz, director Vintage Computer Federation a 501(c)(3) educational non-profit evan(a)vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation instagram.com/vcfederation
