I’m the creator of the SID 6581<>8580 Switcher (here the original project).
I’m Very happy to see my project on the net. Arkanoid (a user of Lemon64 Forum) has done a very nice PCB with some fixes. Very nice job.
This is not a SId2Sid Clone.

The PLA chip (906114-01) used in the Commodore C64 is a generic 82S100 gate array with custom programming.
Its logic functions were dumped and reverse engineered by the community and are available from a variety of sources. This PLA uses the Xilinx CPLD XC9536 to emulate perfectly the PLA of the Commodore 64.

The Commodore SX-64, also known as the Executive 64, or VIP-64 in Europe, was a portable, briefcase/suitcase-size “luggable” version of the popular Commodore 64 home computer and holds the distinction of being the first full-color portable computer.
The SX-64 featured a built-in five-inch composite monitor and a built-in 1541 floppy drive. It weighed 23 lb (10.5 kg). The machine was carried by its sturdy handle, which doubled as an adjustable stand. It was announced in January 1983 and released a year later, at $995.
