Features

Ease of use​

 

  • Automatic SID model detection, any combination of 6581 and 8580 (aka 6582) is supported

  • Manual on-the-fly switching between 6581 (old SID) and 8580 (new SID) while the tune/games/demos are playing!

  • SIDFX support has been built into SIDplay64 and the player of 1541U and 1541U+ by the respective developers

  • Open API for full software control

  • Stereo SID capable with second SID located at either address $D420, $D500**, $DE00 or $DF00***

  • Also works with one SID if you just want to use old SID in new C64 or new SID in old C64

    ** $D500 is unavailable on C128, please refer to the FAQ.
    *** Please refer to the FAQ for instructions and limitations.

Optional accessories

  • SIDFX adapter for C64 Reloaded MK1; our custom adapter that enables SIDFX to fit the ZIF sockets of a C64 Reloaded MK1 motherboard while being mounted in a C64C chassis

  • SIDFX adapter for C64 Reloaded MK2; our custom adapter that enables SIDFX to function with the C64 Reloaded MK2 motherboard

  • Additional accessories are available in our online shop

Sound quality

  • Precision filter capacitors located on the SIDFX module replace those on the motherboard

  • Replaces incorrect filter capacitors found in SX-64 and early C64 models

  • Stereo capable mini phone jack for dedicated high-fidelity output (available in all operating modes)

  • Sample playback fix for 8580 with configurable boost level and manual-/automatic operating modes

  • Reduced audible noise due to individual voltage filtering and regulation for each SID

  • Configurable external audio input mute function for reduced noise

Voltage control​

  • Generates safe and accurate operating voltages for each individual SID

  • Protects SID input and output against over-/under voltage and short-circuit

Installation

  • 4 detachable cables for easier installation and less clutter

  • Two cable lengths, you select the length when ordering. Fits all variants of Commodore 64 and 128
