This would make a great VCF East Exhibit as well as a talk.

Cool project! Did you consider using logic closer to DEC's R-series logic, where flip-flops require only two transistors, with a heavy use of diode-capacitor gates and pulse amplifiers? It seems like this would perhaps be a more efficient use of vacuum tubes, as I would suspect a single (dual triode) tube could implement one flip-flop. Thanks, Kyle

Swap Meet is on! (June 10, 2023)
by Jeffrey Brace 08 Jun '23

We are going forward with the swap meet as planned. After looking at the forecasts for the air quality, the predictions show that things will clear up to acceptable levels by Saturday. I still recommend that everyone bring a high quality N95 mask as extra protection. If any vendor doesn't feel comfortable and wants to cancel before the swap meet, we will issue a refund. On the bright side the temperature looks like it will be 76 degrees and only a 25% chance of rain. New this year we will have food for sale in the parking lot by a non-profit fire museum. I will be setting up at 6AM. Vendors can setup at 7AM. Buyers come at 8AM. Thanks!

Air Quality Index and the swap meet
by Jason k 08 Jun '23

Are there any backup plans in the works if the AQI happens to be bad or hazardous on Saturday? We might get lucky, but it looks like it's supposed to be bad on Friday.

Monroe was 369 at 8PM (yikes) and I can recall it being worse. We had a huge fire in the 70's that wiped out our forests in Monroe. This isn't even close to the smoke we had then (fire was 1/2 a mile away). But now I have asthma and this is nasty. From what I've seen is that the remaining smoke will move further south across Delaware. -- Linux Home Automation Neil Cherry kd2zrq(a)linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies KD2ZRQ

The air's very thick and hazy from the smoke. however, I can't imagine this being any worse than spending an evening camping next to a bonfile or next to a beach kegger with a bonfire.

Re: [vcf-midatlantic] OT: time to downsize
by Bob Shuster 07 Jun '23

Just added: Besides the TRS-80 Model 1 systems, Model 4, Color Computer 2 systems, plus related software and documentation that I added the other day, I’ve also now added all the TRS-80 Model 1/3/4 books that I have. I’ve had a lot of inquiries about the Model 4 - yes, it’s still available until someone commits to coming and getting it! I think I’m going to have to put it back into storage, as I’ve now been using it for days and I don’t want to get drawn back in! ;) I think once I get all the TRS-80 stuff stowed back away I’ll go back and add the assorted items that I found in my closet in the other categories *after* I did the listings. I've been regularly marking the sold and sale pending items, thank you guys so much! And once again - many thanks to those who have adopted some of my babies so far. Please let me know if I can clarify anything or if any more photos are needed. The link: http://www.theshusters.com/bobvintage.html <http://www.theshusters.com/bobvintage.html> Please don't share without asking me. Currently just open to this group - my contact info is intentionally missing from the webpages. If you can read this, you have my email. Email me with questions or offers! Please don't make offers on the list, but if you want to discuss my process and feel the group would benefit, then by all means knock yourself out! :) Bob Shuster (Original message below) ---- Well, folks, I've gotten to the age where I need to seriously downsize my hobbies and collections, not wanting to leave it to my children to have to deal with in later years. (I had to do that recently for a relative.) On the electronics side, I've decided to concentrate on my vintage video game systems - and therefore sell off most of my vintage computer stuff. My collection includes mostly 8-bit stuff: TRS-80 Models I, IV, M100, etc. - Atari 400, 800, Portfolio, ST, etc. - C64/VIC20 - T/S1000 (including an unbuilt kit), Apple II, II+, IIe, IIe Platinum, IIgs - Wang WLTC - Mattel Aquarius - TI-99/4A - many others that I still have to dig out - plus lots of peripherals, disks, manuals, etc. Also have some newer Macs starting with a Mac Plus in an Apple carrying bag. I'm starting with you guys before trying to list elsewhere, although I may hit some of the dedicated FaceBorg pages (such as for Aquarius and Apple II.) I'm willing to ship some of the smaller items, but in general systems or monitors will need to be picked up here (near the Fort Washington exit of the PA Turnpike) or nearby, and cash or PayPal for payment. I may also consider trades for some of the video game stuff I'm looking for. It pains me to do this, but the clutter is getting out of hand, and I haven't touched most of these in years. It's time for someone else to enjoy. Bob Shuster

Slightly OT: Will coding become an intermediate step that no longer will be required for us to perform?
by Bart Hirst 06 Jun '23

06 Jun '23

Well of course WE'LL still keep performing it :) similar to vintage computer knowledge like peeks & pokes, orientation of "pin 1", jumper settings, storage layouts, I/O Port Addresses, IRQ's, DMA, plus many, many more (please list more if you like.) How has the backgrounding of these vintage things (largely unneeded for today's modern computer) yet still relevant, enriching and mind-provoking affected the space? How would the loss of coding impact it? I'm torn. As a programmer, I love a clean piece of code, and at the same time if maintaining other's code, fixing bugs and refactoring could be done using natural language, then sign me up. https://www.youtube.com/watch?v=7yI4yfYftfM&t=1415s <-- link to the part of the video that triggered this email
