mystery continues.... i see a L3 on the pic i have... inside the tin box with the big chip but its on on schematic in refrence guide... and not on the first schematic in the service manual either, but maybe on some of the other schematics in service manual i wonder how they managed to keep track of things.... but hey, who said that the pcb guy at commodore was not a monkey :-D 2017-02-17 23:37 GMT+01:00 Santo Nucifora <santo.nucifora@gmail.com>: > I only see an L5.
