Want to be able to switch between 6581 and 8580 to play/hear all music/demos/games with the correct SID chip?
Just flick the hardware switch to force SID1 or SID2 or put it in auto and let the software decide.
Get your existing SID out of the socket, insert the SID into SIDFX or replace it with any one or two other SIDs you might have. No jumper settings, just connect 4 cables to the unit.
You can customize 3 configuration profiles which can be selected using “switch 2” (one of the cables that comes with the unit).
The configuration tool for SIDFX allows you to set single or stereo-mode, memory-space, specify digi-boost for 8580 and more.
Switch while playing music from one SID to the other, using “switch 1” (one of the cables that comes with the unit).
SIDFX was created so that future SID players can detect which SID models are mounted in the two sockets and set the correct model, if the SID player knows the preferred model for the tune it's playing.
Take any two functioning SID models and put them into any combination in the two sockets on the SIDFX unit.
The unit will auto-detect the models and set the voltages and filter-capacitors accordingly, so your SIDs are safe with SIDFX.
You don't need to solder anything, SIDFX comes as a complete product with 4 cables ready to be attached to the unit.
These are 2 switch cables for manual selections, a mini-jack cable for direct audio-output and a cable with grabbers to allow stereo addressing.
