Special Thanks (belated) to Alex Jacocks
by Neil Cherry 18 Feb '23

18 Feb '23

This is a bit belated (oops). I want to thanks Alex Jacocks for the installation of the door closers in 9059. The doors now close very smoothly and this should help with HVAC costs. Thank you and very much appreciated. -- 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

Re: [vcf-midatlantic] Is the living computer museum dead?

I'll bet she already had a first round, and the initial selling price was rejected by the initial round of potential buyers. She would have top notch staff and people to maximize the price she can get, I would not be surprised if some/all goes overseas. THe US should institutionalize / Smithsonialize this!

Paul Allen's Flying Heritage museum was sold last year. I think it’s clear that Jody Allen has little interest in the enterprise and she controls Vulcan. It's my uninformed option that they may be waiting or looking for a buyer (perhaps even the right buyer that would continue Paul Allen’s Legacy). -Mike Willegal

TTL USB dongle to 5V TTL serial.
by Neil Cherry 17 Feb '23

17 Feb '23

This is not a RS232 USB dongle which has it's own issues with interfacing to older equipment (but same problem, no enough current to push or pull the signal). I have a 3v3/5v0 USB TTL dongle. It works with some equipment but it couldn't pull the signal to 5v0 interfacing to my HD6303 (Hitachi's 6803). I fixed this by using 2 gates on a 74LS04 with the USB dongles TX. Not sure how to solve this. Has anyone built such a set of line drivers? I'll be using a similar setup with a few other boards (EPROM burner, PT69-5, Microbox II, etc.). But those might be worse as I'll be using a ESP WiFi chip (3v3) as a terminal server. -- 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

Repair Workshop 2023-02-11 & 2023-02-12
by Jeffrey Brace 17 Feb '23

17 Feb '23

Wow! What a great workshop. We were all packed into CDL and the adjacent classroom space. We had four new people come to our repair workshop which is great! It's good to have new blood and keep a regular group coming. It seems that the new people were referred to us by other members. One Member, Jim Preciado, said in an email to me: *"Jeff,* *Please pass my thanks onto all for a weekend well spent at your Repair Workshop.You may also pass my contact information onto any of the VCF staff that has a need for it. In particular, please make sure that Doug has it for the museum and the MicroVAX II.* *Thanks!"* ================================= Jeff Brace VCF National Board Member Chairman & Vice President Vintage Computer Festival East Showrunner Vintage Computer Federation is a 501c3 charity https://vcfed.org/ <http://www.vcfed.org/> jeffrey(a)vcfed.org

My video on the PDP 11/73 I recently picked up.
by Dave Shevett 14 Feb '23

14 Feb '23

Hey ya'll. I'm hoping to put together a series of videos on getting my PDP 11/73 up and running. The first video was just posted, I'm hoping folks can take a look and give me some feedback and some love on it. I've spent the last 2 months or so assembling and editing this video, and learned a lot about how to use software that is wildly unfamiliar to me. It's been fun! This is the first video of a series of getting this machine up and running - I have the next 2 videos uon the editing table, but I'm looking for feedback on this first one to help me style the next one. A like, a subscribe, and a comment goes a LONG way in Youtube land, I know folks aren't thrilled with promotional stuff, I do apologize, but this seems like a great way to spread the word on how awesome these machines are, and how exciting vintage computers can be. So, enjoy - please let me know what you think, and share it around if you think others might be interested. https://youtu.be/h6zdf0O1Qo0 -dave s. -- Dave Shevett shevett(a)pobox.com

Don't turn on the Fredon Flexwriter!
by Neil Cherry 13 Feb '23

13 Feb '23

Ian and the other gentleman working on the Fredon Flexwritere, please note: I think the diodes are wired in wrong. https://forum.vcfed.org/index.php?threads/friden-flexowriter-terminal.12417… It just dawned on me that the motor takes 100v DC and I looked at the above. The selenium diode (ah what a smell) may not work the way you think. Here's a schematic but it's hard to read. https://collections.museumsvictoria.com.au/content/media/21/535271-small.jpg http://www.bitsavers.org/pdf/friden/SP8673R2_Friden_Flexowriter_Programatic… I think the selenium diode is setup as an AC Full Wave Rectifier. We should have one of those. We should be able to figure out which wires are which. But the current wiring won't work. -- 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
