Well, compared to the NMOS-Chips from back then, most microcontrollers would be power savers, even when running polling loops. According to the data sheet, a 6567 VIC eats close to 1.5W (200mA @ 5V, 40mA @ 12V). Gerrit Message was sent through the cbm-hackers mailing listReceived on 2012-02-27 20:00:57
