This one needs a little hack to re-enable playback of samples the way the 6581 could and also sounds differently. People have claimed that the 8580 works like its described in the data sheet... (the 6581 only kinda does). > > > These chips are both in the C64C in the states. It was the first C64 I got, and I was confused why people thought the Skate or Die song was so good. It had digi-guitars. Then I heard it on a friend's computer and thought mine must be broken. :-) The trick to 'fix' the 8580 was to pull the EXT_IN pin (!) to GND via a 330 KOhm or larger resistor... Makes me wonder what that does inside the chip. Gerrit Message was sent through the cbm-hackers mailing listReceived on 2011-08-25 19:00:18
