Yes, it is repairable, I've fixed a few - you can replace the individual switches, and you can also clean them. Disassembling the 500XJ is a bit tricky, because of that red/black sticker that holds it together. When I've repaired these, I just slice through the sticker at the seam with a knife, it's not too noticeable once reassembled. Take the stick apart, and find the faulty switch. Try to get as much isopropyl alcohol inside the switch as possible (sometimes I even submerge it in a little cup), and click it repeatedly, and firmly, for at least a minute. Let it dry thoroughly, and check it with a multimeter - most of the time, this will fix it. -Ian On Sun, Dec 20, 2015 at 11:00 PM, Jeffrey Brace via vcf-midatlantic <vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:
Does anyone have experience repairing joysticks? I have an Epyx 500XJ that doesn't respond well to the left direction. I'm just wondering if this is something that is repairable.
