This was one of the better workshops in recent memory, I had a great time. As is typical I ended up working on a bunch of little things. I got in late Friday night as I'm pretty far out of town and fiddled around with a free Sony VCR which I eventually condemned due to impossible to repair cap corrosion damage on a ceramic hybrid module in the video path. I also brought an older Trinitron TV which I cleaned up, fixed and calibrated to give to Ian L as he needed a good looking set with composite. For the other Ian I brought a handful of boat anchor tube scopes and a Packard Bell color TV to downsize a little bit. On Saturday I poked around a black and white Philco-Ford TV and was able to get it to produce a really crappy, inverted picture (after blowing up one of my clip leads when the main filter cap shorted). It uses a bunch of early and unreliable epoxy dome transistors in the IF and video path so my guess is one of them is bad, but I didn't end up having time to troubleshoot any further. Sunday I mostly helped Thomas out with museum stuff, I recapped the boardset out of the Philips CD-ROM drive and got a list of caps to buy for the Personal Iris power supply. It has a fair bit of cap corrosion damage as is typical in those systems but I think it will be repairable, I just need to get the parts and spend some stripping & cleaning it down the road. I also fixed one of the CDL's power strips which may or may not have blown up due to some shenanigans involving plugging caps into the wall outlet...but that's neither here nor there ;) +1 for going back to Patrick's Grill, the food was great and very reasonably priced as far as the 2023 economy is going. Although I personally thought it was hilarious watching the Sunday Night Football crowd go nuts I think it might be for the best if we reschedule to some other time though!

Seems like everyone had fun this past weekend with the repair workshop. The usual suspects were there. Lots of interesting stuff getting fixed.
David Gesswein repaired the VCF Museum's Xerox as well as the Sol-20. Thanks so much Dave!
One lady came who needed picture files recovered from her early 2000's Macintosh. Dan helped her to recover and transfer most of them.
Bill Dromgoole worked on the Univac a bit.
Thomas worked on the Iris Personal as well as The Philips CD-ROM. Supposedly this is the first CD-ROM drive ever made. Very cool.
For dinner Saturday night we split into two groups half went to Brick House Tap & Tavern, the other half went to MJs. Both were good. Sunday night we tried a new place Patrick's Grill and the 8 of us really liked it. So I will make reservations next month for this place.
Anyone else want to chime in on what they worked on?
