 ==== Power Supply ====
-SID power consumption during normal operation is 600mW.
+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.
 === VCC - Pin 25 ===
 This pin shall be powered by a 5V DC coupled power supply.
-About 70mA is drawn from VCC during normal operation. Coupling capacitor of at least 1uf is recommended for proper operation.
+About 70mA is drawn from VCC during normal operation. Coupling capacitor of at least 10uf and filtering capacitor of 100nf are recommended for proper operation.
