New 2023 build - FM Radio Module For the Commodore 64 & 128 by Timo Voutilainen  We have given the FM Radio a major make over! Where to start, we have taken all the elements and combined them on one PCB which plugs directly into the Commodores user port.  We now use a telescopic antenna, which can be easily plugged in and out as needed. Plus there is a new daughter board connector. You can plug in a RTC DS3231 Module to add date and time stamps, the DS3231 uses a CR2032 battery or LIR2032 (Not included). LIR2032 can be recharged automatically by the DS3231. The DS3231 also has onboard storage and can save all your favourite radio stations. The software has also been updated to include all the latest releases - AudioEX 2.0 FM RADIO v2.6 FMCD64 v1.0 Plus the new all new GEOS App and the Commodore 128 FM RADIO by Particles BBS. Sold with permission from Timo Voutilainen & Particles BBS. Simply plugs in your User Port and you can listen to the radio on your 64 and 128! Wor...

  Commodore 64 SID Symphony II/ SID CART for MOS 6581 SID Chip 6581 SID Chip is NOT Included - Cartridge PCB as shown. The SID Symphony II can be mapped into any 32-byte slot from $DE00 to $DFE0, and should be work fine alongside most other hardware expansions. Works with all stereo-aware software that can address a SID in the above range. It is possible to add a jumper to the cartridge to pick up other page address signals inside the computer (such as $D7xx in the C128). Each board features an access LED, reset button, and a proper 12v DC-to-DC converter for use with the good old 6581 SID chip. Each board comes preset for $DE00, which can be changed by flipping one or more DIP switches. The audio-in line is grounded by default to reduce background noise, which one can undo by simply cutting a jumper pad. The SID Symphony II is supplied without a SID chip, and is designed to fit into standard Commodore-issue case shells and their clones. Available from stock £34 plus postage. Simpl...

C64 Replacement RF Modulator Design by Matt Barszcz The C64 RF Modulator replacement based on the schematics of similar designs like Zero-X/OMS's Modified Commodore RF Modulator Design and JMP$FCE2's S-Video only design. This board can be used to replace a damaged or defective RF modulator in your C64, to improve the sharpness of your video output, or as a modern solution to replace the composite/luma/chroma output functionality of the original modulator on new motherboards such as the SixtyClone or Bwack’s KU-14194. This design has a few goals that set it apart from the others - • It is a universal solution that fits and is electrically compatible with both the C64 and C64C without having to change components on the board or run jumper wires for power. • It is easy and inexpensive to build with only a single, small PCB and all through-hole components. • It provides high quality S-Video (Y/C) output while maintaining composite video output for compatibility. • It provides adjus...
