I had brought 2 commodore 1541 floppy drives to check out. One was not worth repairing and the other one I just basically swaps out some parts. I got drive 2 working, so I have one good drive and one drive for parts. I plan to use the power supply from drive 1 to make a more sturdy Commodore 64 power supply, eventually. I also brought a Zenith remote control black and white TV that had been sitting in my garage for nearly 20 years. I put it on a Variac to start for a few minutes and then put the voltage up to full line voltage. It worked with just a few adjustments and it worked well. I ended up giving it to Ian. My AmStrad gaming system still needs a memory IC, which I have to order. Ian brought his, so we can do some quick testing and it did seem to want to work, even without a second memory IC. I did find some books and magazines that were being discarded which I could use. Thanks for Jeff’s help and for Ian‘s help on Sunday. And the bagels from Bill. Sent from: My extremely complicated, hand held electronic device.

We had 10 people come to our repair workshop. It was very successful and everyone enjoyed it. We seem to have a pattern that works for everyone, so we will repeat it for the next workshop on August 15 & 16.
I worked on recovering data from a modern hard drive Jonathan and Ian helped), which I will detail in another email. I also was successful in repairing a Rev A Commodore 64 board. Alex Jaccocks and Jonathan Sturges helped me. It had bad Character RAM (U6), Character ROM (901225) and a bad U1 chip (6526). This Rev A board has a ceramic VIC 6567 chip too!
Bill Dromgoole successfully repaired the museum's Ohio Scientific computer. There were 3 keys that needed replacing.
Ian fixed one of his black and white TVs and worked on many other things with others.
Neville worked on his Kay Pro. I'm not sure how he made out with his repairs.
Mike Rosen worked on Commodore 1541 repairs.
Ian and Jason Perkins also worked on scanning some documents from the museum warehouse for preservation.
Don't know what Alex Jaccocks and Jonthan Sturges were working on.
Bill Indereidden continued to document and work on the Wang 4000.
Maybe everyone can tell what they were working on and their progress.
Next workshop is August 15 & 16: Sign up here: https://docs.google.com/spreadsheets/d/1L3Jc_RIHiBG08kZOOAgzvqjf8G0ox9ZRa6Bn...
There will be a limit to 10 people in the workshop area. If more want to come, then there is room for 2 or 3 people in the museum workshop space. Face masks are required for this gathering. -- ========================================= Jeff Brace Vice President & Board Member, VCF East Showrunner Vintage Computer Federation http://www.vcfed.org/ jeffrey@vcfed.org
