allows you to install any two versions of the SID into your Commodore 64
SIDFX allows you to install any two versions of the SID into your Commodore 64, SX-64, 128, 128D or C64 Reloaded, both PAL and NTSC, and switch between them.
It's plug-and-play, no jumpers or configuration, the SID versions are automatically detected, and the physical switch allows you to switch between the two chips mid-tune.
The current batch is the last, because of obsolete components, so when they're gone, they're gone.
460 DKK is around 63 EUR, around 53 GBP or 70 USD.
