+ | SID power consumption during normal operation is around 600mW. Expect a little more from a 6581 (around 650mW), and less from 6582 and 8580 (around 550W). | ||
+ | The SID shall heat a lot during operation. The design of the analog part of the chip has been improved from 6581 to 6582/8580, allowing to reduce the operating voltage of the chip, and at the same time lowering its consumed power. | ||
+ | |||
+ | This also means that 6581 and 6582/8580 __are not compatible__. The power voltages listed below shall be respected, otherwise SID might be damaged. | ||
