Mike, Glad that you could make it and had a productive workshop. Next time I will have one or two C64 parts machines available. I also have some extra chips such as PLA available. Alex J told me about Forever PLA. I will look into buying some. The C64’s PLA was notorious for failing. I will also dig up a C64 diagnostic that uses LED lights to tell which chip is bad. This is useful when there is no video working. On Mon, Jan 14, 2019 at 1:05 PM Sentrytv <sentrytv@yahoo.com> wrote:
I worked on my Atari VCS system to get it working and for sale.
I also worked on three Commodore 64 units and learned quite a bit about the diagnostic tools available to plug-in and see which chips possibly could be defective. Unfortunately I couldn't repair any because I need the chips, but it was a it was a productive day.
I learned from Chris and Todd, (forgot last names) about these tools for diagnostics.
I met another Mike who also had Commodore 64 to work on and try and repair.
Workshop definitely had more people there than the last time I attended and I will most likely attend the next one.

The workshop was great. I estimate that on Saturday there was about 20 people there. Lots of things fixed. I started evaluating my many, many C64, but didn’t get very far. I will get started earlier on Saturday next time as many people do one day and leave early.
Who else wants to tell what they worked on and fixed?
