Introducing the Low Noise A/V Replacement for Commodore 64 and Commodore 128!
This replacement offers S-VIDEO and AUDIO outputs, along with jail bars removal circuits.
It is compatible with both long and short board revisions of Commodore 64 including the MAX MACHINE, as well as Commodore 128.
Here are the improvements made to the replacement:
- Added jumpers for selecting the board revision (long or short) and removal of 9V external wires
- EMI filters have been added to reduce high-frequency noise on the power rail
- Only two wires are required for AEC and PHCL signals from the motherboard
- The composite signal is now processed by the video amplifier THS7316
- Short board and C128 no longer require the use of 7805
- Clear silk screen layers have been implemented
Please note the following:
- AEC and PHCL, EXTERNAL AUDIO(optional) signals should be connected using short and shielded cables
- In both Commodore 64 and Commodore 128, AEC is pin 16 and PHCL is pin 21 of any VIC-II version
- In the C= MAX MACHINE (equivalent to a C64 long board model), AEC is pin 16 and PHCL is pin 19 of the MOS6566
