From the project
There are many Stereo SID boards, but this one in mine... Add a second SID of the same type or newer substitutes for adding stereo audio to your system...
There are many Stereo SID boards out there, but this one is mine - mostly because I did not feel like tracking down or paying premium to get one of those wirewrap sockets. Using a simple board like this will put a second SID chip at $DE00 and add 3 voices to your system, with suitable software and a selection of SID files you can play music on your system like never experienced before (your mileage may vary)! For everyday use you can use it in pseudo stereo-mode by having each SID play the same thing simultaniously.
