Just a heads? up to the group that I am not using this any more; ever since I restored the PLATO terminals for LCM and CHM, I have not touched the 29B. I don?t think that I am going to be having much use for it since I have not been dabbling in vintage hardware. If anyone is interested, it is listed right now; but I am more or less interested in giving it a good home and if someone wants it, just contact me directly and I?ll be happy to try to make that happen (and I can remove the auction if nobody has bid). https://www.ebay.com/itm/233305501413 <https://www.ebay.com/itm/233305501413>

Anyone have one of these? I'd like to find a system, but images of the OS media would be interesting. Regards, Kevin

Avoid shipping with pre-sale deals on stuff from Sellam's collection--today only!

by sellam.ismail＠gmail.com

Howdy Folks. I wish I had thought of this a few days ago, but I wasn't sure if I was going to be making it to the VCF event this weekend. Being that I am, I'd like to offer to bring any item that you want to purchase to the VCF if you're going to be there yourself. That way you can save on the shipping. Also note that I have "show prices", which are higher than my normal prices to offset the consignment commission. However, if you confirm a purchase beforehand, you will pay the regular asking price. The listings on my Virtual Warehouse of Computing Wonders are presently up to date: https://docs.google.com/spreadsheets/d/1I53wxarLHlNmlPVf_HJ5oMKuab4zrApI_hi… Please be reminded that this is not my complete inventory, but merely what I have presently processed and listed from my warehouse mine. If there's something you are looking for that I don't have listed, please send a request by e-mail. Thanks! Sellam

VCF Midwest 14 Overflow Hotel Block Open

by silent700＠gmail.com

Hello vintage fans! This is exactly the kind of problem a growing show wants to have, but it's a problem nonetheless. The Clarion Inn hotel attached to our show venue is FULL for Saturday night 9/14. There may be a few rooms left for Friday 9/13, but that doesn't do you a whole lot of good if you're staying the weekend. We have arranged a small room block at the Comfort Suites in Oak Brook Terrace, a short drive away from our hotel (sadly there was nothing nearby that was walkable). Room rates are the same ($109/night) and we have King and Double rooms reserved from Thursday through Sunday nights. More information and a booking link can be found here: http://vcfmw.org/hotel.html We recommend checking with the host hotel (Clarion Inn, info at the link) first in case a cancellation freed up a room before booking with Comfort Suites. And remember - the deadline to book a room is August 24th. They're not going to let us slide! Looking forward to seeing everyone there in September! -jt

What's a half meg on the Atari800 good for under

by technoid6502＠gmail.com

Good question. There are upgrades up to 4mb, but ones for the 800 most common range from 64k to 1088k. A pair of really common and several less common standards have existed for many years. This one conforms to the Axlon standard, which is among the oldest for the Atari's. It switches the banks in 32k increments. The other standard was set by Atari on the introduction of the 130xe; that switches in 16k increments. Aside from a ramdisk, what can you do with it? My primary reason for building the thing is to gain memory for the Spartados X operating system, which benefits greatly from more memory (256k is the sweet spot). SDX barely runs on 48k ram and the SIDE driver does not load. SIDE2 is a cartridge for the machine that grafts a CF slot on and allows it to act as a hard disk under SDX. This is of course very useful. Here's a link to the Spartados X cooperative: http://sdx.atari8.info/index.php The Side2 cart, in addition to hosting Spartados X and the CF hard disk controller and firmware, also hosts a real-time clock, and can carry several other programs which must be hosted by hardware because of thier bank-selecting rom design, such as Basic XL, Basic XE... Spartados is a 256k bank-selected cartridge itself. Released in 1988 by ICD, Spartados X is a surprisingly rich disk operating system which adds a host of features not available on other 8-bit machines. IO redirection and batch processing, memory management, paths of various sorts... Here's a link to the Side2 cart, which comes with the SDX firmware pre- loaded: https://lotharek.pl/productdetail.php?id=55 Being able to load the SIDE driver and access the CF slot as a hard disk is my primary purpose. The machine will have ample memory to run real programs while running SDX, which is also very important.

512k SRAM for Atari 800 computer

by technoid6502＠gmail.com

I'm building as many as ten of a 512k Axlon compatible memory board for the Atari 800 (not xl) computer. If you'd like to have one, please message me and let me know so I can reserve one for you. I'm not sure of my cost at the moment, but it is something on the order of $30.00 per board. I'll tot things up when I get around to it, but it will probably come out to less. So for parts and shipping, you can have one. Here's a photo of the completed board: https://atariage.com/forums/topic/256464-designing-an-axlon-compatible-boar… https://atariage.com/forums/topic/256464-designing-an-axlon-compatible-boar… I've got all the parts on order but the boards, for which I'm waiting for a quote. I gather the boards are about $10.00 each but am not counting my chickens quite yet. Best, Technoid Mutant

Announcing Cadetwriter

by dave＠babcock-family.org

To all, After several more months of delays - personal and project issues - Cadetwriter is being released.? [Cadetwriter is the official name of our general-purpose, Wheelwriter-based Computer Terminal.]? The public unveiling will be at this weekend's VCF West at the Computer History Museum in Mountain View, California. Attached is a flyer on the device. At the show we'll be demonstrating the Cadetwriter connected to: ??? ??? *? IBM 1620 Jr. via USB & proprietary protocol ??? ??? *? ALTAIR 8800 replica (Chris Davis) via RS-232 running OS/8 ??? ??? *? PiDP-8/I replica (Oscar Vermeulen) via USB running MITS Extended 16K BASIC (Bill Gates, Paul Allen, Monte Davidoff) ??? ??? *? Windows laptop via USB and a USB->RS-232 adapter Our plan for the show is to invite anyone with a computer having an RS-232 or USB port to try out Cadetwriter with their computer. We're hoping for a lot of takers We're finishing getting the documentation written or updated and everything uploaded to GitHub.? It should all be available next week. We appreciate your patience. Thanks, IBM 1620 Jr. Team

looking for a 7-track reel tape controller

by p.gebhardt＠ymail.com

Hello list, I have been looking for years for a q-bus or unibus-based disk controller that is able to handle 7-track drives (NRZI encoding). So far, I only located one controller type which handles that: Dilog DQ120 or DU120 and I never came across any. Any other suggestions regarding controller types?Contact me off-list if you are happy to part any 7-track tape controller with me. That would be very much appreciated :) Best regards,Pierre -----------------------------------------------------------------------------http://www.digitalheritage.de

A few VT-320 and keyboard questions

by athornton＠gmail.com

I just picked up a VT-320, with no keyboard. I have some questions: 1) the price on DEC keyboards, at least on eBay, is insane. Does anyone have a VT-320 keyboard they?d be willing to let go cheaply? 2) ?or, failing that, I found a posting of someone who?d done an Arduino-based key code mapper that let him use a PS/2 (or maybe it was an AT) keyboard as a replacement. The link to the actual project was dead, though. Anyone have schematic and source code for such a project? 3) If anyone's got a DB-9-or-25-to-MMP cable you?d sell cheap, I?d be happy to buy it instead or making my own. OK, that?s not really a question. There?s a blank insert where the 25-pin connector usually is; was that a ?feature? of the B2 model? (that?s a question but not much of one) ?aaaaand while I?m here, another question. 4) I have a number of Apple IIs and one III that have sustained some keyboard damage. Where can I get/what is the name of the little plus-shaped keyboard stems for those? If I had a couple dozen that would be most helpful. Adam
