Any trick to discharging ADM-3A
by corey cohen 10 Feb '18

10 Feb '18

So I was about to swap out my ADM5 for my ADM3a with my ALTAIR and realized while I did replace the electrolytic and tantalum caps on the main board, I didn’t change the electrolytic caps on the analog board behind the tube. No big deal except that the rubber cup is on the top where I can’t get to it without removing the tube and you aren’t really supposed to remove the tube till you discharge it under the rubber cup. So chicken or the egg? Or am I just supposed to let the ADM sit unplugged for a few weeks and just assume it self discharged? Just when I thought I was finished with this project and was going to move onto my TI silent rebuild. Thanks, Cheers, Corey corey cohen uǝɥoɔ ʎǝɹoɔ

Interest Check: Belden Thicknet 10base5 Ethernet Coax
by systems_glitch 08 Feb '18

08 Feb '18

All, Per the recent cctalk discussion on thicknet/early Ethernet, I figured I'd see if there's any interest in cut-to-length Belden thicknet/10base5 Ethernet cable. I've got a local surplus guy who's got at least one 1100 foot roll. It's the real Ethernet spec stuff, sez so on the cable, and it has the bands to locate your vampire taps. If there's enough interest, I'll buy the spool off of him and cut it to length for whoever's interested in buying some. I can crimp N terminations on as well. Thanks, Jonathan

WTB: Cisco IGS

I'll keep you in mind. Yes, the IGS was a 68k-based, fixed-port (1 AUI ethernet and 1 sync serial) router. It was contemporary with the high-end AGS and midrage CGS. Ran IOS out of ROM, and upgrading required a physical ROM swap. Mine was IOS 8, but I think there was an IOS 9 update before the IGS was replaced by the c2500 series. KJ

Anyone have an old IGS kicking around? I've been working on my DEChub 90T1 and would like to see just how similar the two are. Thanks, Jonathan

Craigslist Philadelphia Posting
by Joseph Oprysko 08 Feb '18

08 Feb '18

There is a person posting a fair sized lot of Apple hardware in the Philadelphia area. Personally, I think as a LOT price, he’s asking too much. But that could just be me. He likely priced out the pieces then added all the prices together. https://philadelphia.craigslist.org/sys/6477834592.html -- Normal Person: Hey, it seems that you know a lot. Geek: To be honest, it's due to all the surfing I do. Normal Person: So you go surfing? Normal Person: But I don't think that has anything to do with knowing a lot... Geek: I think that's wrong on a fundamental level. Normal Person: Huh? Huh? What?

hard drive repair service, at Trenton Computer Festival?
by Herb Johnson 06 Feb '18

06 Feb '18

In 2017 or 2016, at the Trenton Computer Festival, one of the "flea market" vendors was a hard drive repair service. They had a table covered with opened-up hard drives. Does anyone have a name and point of contact for that vendor? The TCF (TCNJ) Web site doesn't have lists of vendors, barely tracks previous TCF's at all. This is about an 8-inch hard drive, by Priam. I'm not looking for a diagnosis or discussion - just a repair service. I can search the Web, so I'm not asking for that. But if someone knows of a large hard-drive repair service still active today, I'd like to know. Contact me via my Web site (see below) or privately at my email posting address. I suppose we can discuss these services "here" in the list but mostly this is a commercial request. Herb Johnson -- Herbert R. Johnson, New Jersey in the USA http://www.retrotechnology.com OR .net

Here's a sneak preview of the shirt design for all of our 2018 events. As usual, each event will be a different shirt color. Any similarity to a certain VCF/MA member in Pittsburgh is purely coincidental. :) https://vcfed.org/wp/wp-content/uploads/2018/01/pnw-shirt-front-1.png
