Hi any idea if +12v and -5v are used for anything else than the 4116 ? the idea: all original regulator removed (easy to put back in place) (+5 +12 -5 disconnected from the original power supply) +5v regulated directly injected on the motherboard +12V connected to +5v regulated (strap between the 2 regulator output ) 4164 installed in place of 4116 the 4164 would get 5v by the 12v track (now 5v with the modification) pin 1 -5v not connected (-5v removed) pin 8 +5v (+5v coming by 12v track) pin 9 A7 (forced to 5v by 5v track) seems similar on some modification made on atari may any potential side effect on some other part of the system... I dont see any real use of the +12v and -5v except for the 4116 but I might have missed something for the +9v unregulated I never found any used except for the tape but I'll probably never use a commodore tape... the main idea is to avoid any permanent modification on the board... -- didier Message was sent through the cbm-hackers mailing listReceived on 2016-09-07 12:00:04
