Thanks guys, very helpful! See you it he morning with a lot of Commodore. :-) On Jan 29, 2016, at 6:14 PM, william degnan via vcf-midatlantic<vcf-midatlantic@lists.vintagecomputerfederation.org> wrote: I guarantee the number of repaired drives will be a function of the number of available ROMS, as these and the maybe a few key caps will be the failure point for most drives. Maybe a few can be fixed with alignment and cleaning but the ROMS and other chips are the big culprits. Expect instead that you can borrow enough parts off of each set of 5 drives to make one working drive. I'd expect that there are a lot of lost case drives at VCFs inventory and Ebay at this point. b On Fri, Jan 29, 2016 at 5:49 PM, Jeffrey Brace via vcf-midatlantic < vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:
Chris,
I was wondering the same thing. I would say from experience with repairing Commodore 64s at the workshop, I would bring 5-10. Some you would use for parts, but I would expect at least 5 can get fixed. But this workshop is unusual because we got a lot of people that know their stuff coming to help and lots of people working on fixing. If you want to bring 20, that is great. I wouldn't expect all to get fixed, but there is a great possibility that they can. For myself I will bring 5 working drives, and 10 non working drives. Some of them I have labeled as to the dysfunction with a post-it note. I don't have a lot of experience fixing them, I have tried cleaning some and they remained unfixed. My gut tells me that a smaller percentage can be fixed with cleaning them 10%, a bigger percentage could have chip issues like 25%, maybe 50% have component issues (capacitor, resister etc.), another 15 percent are disk head or speed issues. What does everyone else think?

I have been really looking forward to an opportunity to get some experienced assistance repairing 1541 drives. I acquired several on eBay and other sources over the last couple years. Some were functional, some worked after the heads were cleaned, and some are still malfunctioning for unknown reasons. I haven't had the time to dig deeper and diagnose the problems on these. I hope that I can learn more about these this weekend and get at least some of this last category working.
Practically speaking, how many drives should I bring this weekend? Is 20 too many or is it possible to actually work on that many in a day? Are there common problems that can be addressed quickly, or is it more likely that each drive will require unique troubleshooting?
