+chue Posted June 20, 2017 Share Posted June 20, 2017 (edited) I recently acquired a Triton Super XB cart and am having trouble booting it. I have 2 TI's and it doesn't boot in one of them. On the other it boots if I have it seated just right. I really can't explain what "just right" means - it takes a few tries fidgeting with the cart. Once the cart is bootable, it will always boot until I pull it out of the slot. I've already reseated the socketed chips, and I think I will try replacing the capacitors next. I just want to make sure I have the right values though... As far as I can tell there are two types, but I need some help identifying them. The first type is an orange one with the marking "33-16". Google tells me that this is a tantalum 33 uF cap. The second type is a blue one that has the marking "104M". This appears to be a 100 nF ceramic cap. Pics of caps and cartridge board are attached. Am I right on the cap identification? Is there something else I should be doing with the cart to get it to boot?

atrax27407 Posted June 20, 2017 Share Posted June 20, 2017 Try cleaning the finger contacts on both sides with a rubber eraser. 1 Quote Link to comment Share on other sites More sharing options...
+adamantyr Posted June 20, 2017 Share Posted June 20, 2017 I've got a copy of SXB from back in the day and I have noticed it's gotten a little "glitchy"... I probably should clean up the contacts and see if it continues to misbehave. Quote Link to comment Share on other sites More sharing options...
+arcadeshopper Posted June 20, 2017 Share Posted June 20, 2017 many times it's your cart ports that are the issue, but that board looks pretty dirty as well, some deoxit would be good or at least clean with a pencil eraser.. more info on this process: http://mainbyte.com/ti99/minimem/cart_fix.html Greg Quote Link to comment Share on other sites More sharing options...
+chue Posted June 20, 2017 Author Share Posted June 20, 2017 The only thing harder than cap identification is finding an eraser! I found some other rubbery-like material and tried cleaning the contacts with that. You guys were spot on to try cleaning the contacts. It now boots in the TI that didn't boot before. I still have to do some fidgeting with the cart though. I'll try a real eraser next (I have to go buy one), and after that some cleaner as Greg suggested. Thanks!

Omega-TI Posted June 20, 2017 Share Posted June 20, 2017 After you get the contacts nice and clean, lay a thin coating of solder on them. 1 Quote Link to comment Share on other sites More sharing options...
+Lee Stewart Posted June 20, 2017 Share Posted June 20, 2017 ... I'll try a real eraser next (I have to go buy one), and after that some cleaner as Greg suggested. If it is not on the end of a pencil, be sure you get a ruby eraser (not artgum) because a ruby eraser should contain fine abrasive material (pumice, etc.) that will aid in wearing off the oxidation from the contacts. ...lee Quote Link to comment Share on other sites More sharing options...
