Yep, there is a 2909 on board too.... ;) - Mike: dogas(a)leading.net

I've got one of those too. What a cool board! I *really* like Am2901s. -Dave McGuire

Yeah, I've just never gotten a close enough look at one to be sure. Other 264X terminals do differ: 2640s have a processor card with an 8008, and I never figured out what the processor was in the 2647F. > Thanks for the info! $300 is more than I want to spend on this one, but I > may have to figure out something if my patience starts to run out... Hey, this isn't for a PDP-11 or a VAX, it's for an HP3000, which is God's gift to computing. -Frank McConnell

ANNOUNCEMENT: Electronic/Radio/Computer Swap

by kyrrin＠bluefeathertech.com

The annual Mike and Key Amateur Radio Club swap meet is coming up again at the Western Washington (Puyallup) Fairgrounds on Saturday, March 11, from 09:00-15:00 Pacific time. Parking is free, admission is $6.00 with kids under 16 free when accompanied by an adult. Web info can be found here: http://www.mikeandkey.com/flyer00.htm (shameless plug alert!) I'll be there selling this year. Here's a partial listing of what I plan to bring: Exabyte 8200 and 8500 8mm SCSI tape drives, cleaned and checked out. A small (400W or so) UPS. Motorola 'Micor' radios. A Western Electric "shoebox" 1A2 key system cabinet and line cards. Anything else I can think of to grab, and that will fit. I want to bring out some DSD-880's, and maybe a Cipher front-loader, but Eric Smith was supposed to pick such up from me. On the other wing, he did not appear when he was scheduled to, and my E-mails to him have gone unanswered. Eric, if you're reading this, PLEASE GET IN TOUCH WITH ME! I'm willing to hold the stuff you wanted for a reasonable amount of time if you'll just commit to a pickup date. However, I need to clear space for future projects. Thanks for reading, and I hope to see at least some of you there. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com // E-mail: kyrrin(a)bluefeathertech.com Amateur Radio: WD6EOS since Dec.

AT&T 3B2 model 310 and model 400 in Kansas City

by mmcfadden＠cmh.edu

AT&T #B2 model 310 and Model 400 I just ran across these two machine along with some sort of AT&T external case that goes with them. The model 400 has a damaged case, I haven't looked inside. Rare, interesting, should I save them? I have read the 3B2 FAQ. Anybody else want them? Mike mmcfadden(a)cmh.edu

Heath/Zenith stuff

by KB9VU＠aol.com

I have a Zenith (Heathkit) H/Z-110 low profile computer with all the options including the latest MB and 768K of RAM, Dual internal hard drives, outboard 1/2 height 8" Zenith drive unit, the color monitor and the Gemini IBM PC card (boots PCDOS directly). User, Technical and Service manuals: Full, original set. Software: Yeah! Lots of it. 15 to 20 original H/Z 3 ring binders of documentation and at least 150 4.25" disks of software. Operating systems: ZDOS, MSDOS, CP/M-80 and CP/M-86. I need room. Make me an offer. Shipping is NOT desired as it will take 3 or 4 large boxes and a lot of work to do it. Located in the St. Louis area. Jay West is still working through the pile of H/Z-89 stuff he picked up from me last month and I may have a few more items of that vintage, spare parts, software and maybe one more computer, available also. If Jay doesn't want them, they will be available. Again, I really don't want to ship the big stuff. Mike Stover, KB9VU Really great radios glow in the dark CCA# 404 MARS AFA3BO Florissant, MO

Cassette storage

by jfoust＠threedee.com

I received this charming message from someone today regarding the audio storage section of my web page http://www.threedee.com/jcm . - John : ::: From: xxxxx(a)aol.com : :: : Date: Sat, 26 Feb 2000 12:35:59 EST Subject: Cassete tape data storage To: jfoust(a)threedee.com : : : When I first saw your page, I was surprised that such a technology ever existed. Lately, I have been writing a windows program that stores data on standard cassette tapes, like a cheap alternative to a tape backup drive. I, being fourteen years old, was not around when the Commodore and other such systems dominated the market, so I did not know that there was ever a way to store data on cassette tapes. Once I am completely done, and I can fit a fair amount of data onto a cassette, I will send you the program. If you know of any other such programs, please tell me of them. I am interested to find out more.
