Jeffrey Brace jeffrey at vcfed.org Writes:Wed Sep 2 13:48:24 EDT 2020 Sounds like an Outer Limits episode where the world was taken apart and remade every moment and sometimes they made mistakes which is why when you lose your keys you find time in a place that you already searched. I thought this was a Spielberg "Amazing Stories" episode, obviously not. The episode is: "A Matter of Minutes" is the third segment of the fifteenth episode from the first season (1985–86) of the television series The Twilight Zone. See: https://en.wikipedia.org/wiki/A_Matter_of_Minutes I remember that scene where the couple is in the "Void of White Space" and the "Supervisor of the Maintenance of Time" says: (paraphrasing) "Ya know how you go back to look for something you know is supposed to be there multiple times and then it finally is where you thoughtit should be? That's us. We forgot something. We are now working on moving Christmas!" I personally call them the "Minute-Ahead" men and you may hear me at a workshop cursing at them!!!! I DOOO BELIEVE!

Ordering Snark Barker MCA (Sound Boaster clone) PCBs -- Want One?
by Alexander Jacocks 30 Nov '20

30 Nov '20

All, I'm in the process of ordering PCBs for the Snark Barker MCA (microchannel), which was just announced, here: https://twitter.com/TubeTimeUS/status/1333123576346468352 The design files and BOM can be found here: https://github.com/schlae/snark-barker-mca I'll be ordering from PCBway, who does gold fingers, so that the boards will be able to be able to be repeatedly inserted, without wearing out the contacts. Is anyone else interested? The cost (at quantity 5) would be about $34+shipping, per PCB. The cost should go down with a bigger order, should more than 4 others want boards. I could probably be convinced to make the parts order, as well, if folks want. Thanks! - Alex

UPS (Uninterruptible Power Supplies) was: How's Everyone Doing
by Jeffrey Brace 29 Nov '20

29 Nov '20

I decided to make a new thread since there is a lot of interest in this topic, etc. @Dave Mcguire. Thanks for the tip on where to buy replacement batteries. As far as I know APC is the most recommended brand. I see others are using Panasonic. I'm curious to know which brands everyone recommends or discourages?

Attic finds :-)

1 - PT68K-2 loads with OS9 2.3 (I think it's OSK at this point) 3 - I8039 & 8243 <- Wierd, not a chip I typically worked with 1 - NSC8073 Tiny Basic chip 3 - I8052, I think these have BASIC on them 1 - 68020-12 & 68881-12 1 - PEP Eurobus system (68K, 10 serial, 1 LPT, 720K? 5 1/4 Floppy, 20M Hard Disk) 2 - 8088 XT mother boards (?), I never had a DOS system other than my work machines I have to search for my Hercule Video Card. Not sure where that is. I have found my other PT68K-2 with Humbug/OS9 roms. I'll need to replace the 48T08 chips or just drop in 6116 (100 ns) so I can start playing. The PT68K-2 is in an AT case with an AT Power Supply. It must weigh at least 40 pounds. If the floppy drives are belt driven then they're useless but I think this is when the first pancake drives arrived. This system has a 720K 5 1/4 & a 720K 3 1/2. Anyone know the best way to resurrect an old hard drive that hasn't run in at least 30 years? What I didn't find my other 6809 boards or my parts for building those 35 year old boards. I have them somewhere. -- 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
