Just a heads up to those on here who still own/use the Victor line of chargers. There is a guy advertising upgrades/repairs on Ebay for sale. He used to be the service/production manager for Victor Engineering back in the early to mid nineties. He says he has schematics and parts to do repairs and upgrades to convert older IQ series chargers to the 3000 series. His user name is headelectronics, you can find it listed under Victor Engineering.
thanks for the info!! i almost sold my superII because i wanted to upgrade to the 3000 software.. this is the best upgrade you can do fo these old super chargers.. these thigs are charging my 4200 without a problem..
