I'm going to Kennett Classic's event this Saturday, how about you?
by Jeffrey Brace 23 Sep '20

I think this will be a fun event to go to. I'm going to check out the new changes to the museum there and the outdoor event. I also heard a rumor that VCF will have a table there showing off a vintage computer. Who else is going to the event? I'm also looking forward to the dinner afterwards. -- ========================================= Jeff Brace Vice President & Board Member Vintage Computer Festival East Show-runner Vintage Computer Federation is a 501c3 charity http://www.vcfed.org/ jeffrey(a)vcfed.org cell: 732-759-1783

Keytronics repair - not foam related
by Bob Applegate 23 Sep '20

23 Sep '20

This has nothing to do with the deteriorating foam, so don’t suggest that. Has anyone debugged the “later” Keytronics keyboard electronics such as the A65-02495-001 (-01) like used on Franklin computer machines around 1983-1984? I’ve got a few of them where a few keys don’t work and I’m wondering if anyone has looked into what the most likely problem is. There are only seven chips on this model/revision board: 8048 XR 22-908-03A 74LS138 (two of them) 74LS374 74LS74 7406 My guess is that one row/column isn’t being scanned or read properly. Only the 8048 is socketed and NOS 22-908-03As are kind of pricey so before I spend the time to remove the chips I was hoping someone else had debugged this design and could offer a suggestion for what’s most likely at fault. The earlier ACE-100s and early 1000s had a different keyboard that was more generic with an edge connector. Franklin used a small PC board that plugged into the edge connector and then had the typical Apple/Franklin 16 pin IC socket. It also had more chips and an EPROM. The later keyboards had fewer chips and included the proper IC socket. Franklin’s Engineering department had nothing to do with the keyboard design other than providing the specs for what the interface looked like. Ie, I was never involved with the discussions with Keyytronics and never knew of our having source code to the keyboard controller. Any help would be appreciated before I remove/replace chips. Bob

Old TV knocks out internet for entire village

I could go into all the different problems with this but given that we probably all have an old TV or monitor, it is something we may find funny. https://www.cnn.com/2020/09/22/uk/old-tv-breaks-broadband-village-scli-intl…

Weird. I see the HealthKit group, the thread about the person selling the stuff has 15 comments, 2 shares and 36 likes on it. Opens right up in The Facebook app on my phone. I did not try it on a desktop but if you’re logged into Facebook id imagine it would do the same thing.

Re: [vcf-midatlantic] Recapping a Mac IIci
by Ethan O'Toole 21 Sep '20

21 Sep '20

The problem is when the capacitors leak juice out it changes the chemistry of the solder or something. Unsodering leaked caps is often a difficult mess. I don't know if the IIci uses surface mount caps or not. I haven't had one in a long time (but wouldn't mind another one, they are cool. I was eyeballing that one at Festivus or whatever.) One thing you can do, clean it off as much as possible then try to add new solder to the old solder first, then try to desolder it. Another trick is cutting away the old cap first using snips, but this brings the risk of pulling up traces. Similar to the other poster, I always use leaded solder. I don't know anyone that uses lead free at home. On Sat, 19 Sep 2020, Sentrytv via vcf-midatlantic wrote: [NON-Text Body part not included]
