MOS 8580R5 SID adapter. Instead of MOS 6581, we can put it in a longboard (407,425, 466) without modifying the motherboard.

It also works in a 69 motherboard, you can use digifix there as well.

DIGIFIX can be switched on with a jumper. With this, the digitized sounds will sound normal with 8580 SID as well as with 6581.

In test 586220, due to the different value of capacitors c48 and c93, the test displays a control port error with SID 8580. Here, when switched on with the jumper, the test will receive a suitable value and will not display a control port error. If your sid is otherwise good.
