FPGASID

Introduction

The chip MOS6581 also known as the Sound Interface Device (SID) of the Commodore 64 computer is known for it's characteristic sound. Unfortunately, many of these devices produced between 1982 and 1993 reach the end of their life span these days. It is getting harder to get a replacement part. Thus, we need a proper substitute.
And this is what the FPGASID project is all about!
It has been started to overcome with this situation and reaches even higher - it aims for a better SID than any SID has ever been before...

The Mission

  • Create a pin compatible drop-in replacement for the MOS6581 device as well as for its successor, the MOS8580.

The Targets

  • To-the-cycle exact reproduction of all digital parts including sound and envelope generation and paddle readouts.
  • Exact modeling of the analog parts leading to a result that is almost indistinguishable from the original.
  • Making it configurable to easily switch between various SID variants
  • Adding extra features like wavetables, stereo sound, more voices etc while keeping full compatibility.

The Means

  • Use of FPGA technology. It is more suitable than software related emulation.
