 +====== FB-SSID (Stereophonic-SID) ======
 +
 +This page contains the most essential parts of the {{:​base:​fb-ssid-rev1a1.pdf|FB-SSID manual}} for revision 1A1 of the hardware.
 +
 +The FB-SSID is compatible with both Commodore 64 and Commodore 128 computers and is available in two versions. One is designed to support a 12Volt 6581 SID while the other is designed for a 9Volt 8580 SID. A pass-through cartridge slot is also included intended for use with the Prophet64 cartridge. However, other cartridges like the Epyx Fastloader may also function when plugged into this slot.
 +
 +The FB-SSID includes an 8-way DIP switch and IO1/IO2 jumper used to configure the memory address of the FBSSID. The default memory address is $DE00.
 +
 +Pin 8 of the DIP switch is the one closest to the edge of the circuit board. Pin 1 of the DIP switch is the one closest to the SID chip.
