Newsgroups: comp.sys.atari.st Subject: 6581 (SID to you) Message-ID: <9003080812.AA27742@ucbvax.Berkeley.EDU> Date: 7 Mar 90 17:35:00 GMT Sender: usenet@ucbvax.BERKELEY.EDU Organization: The Internet Lines: 11 I am in need of hardware information on the 6581 sound chip (ie SID in the Commodore 64), in particular the data sheets. I am also possibly interested in getting hold of some 6581s, but have found them somewhat expensive (around 15-20 pounds), which is made worse by the fact that I may want about 8 of them!! Anyone know where I can get hold of these cheap?? (Apart from by cannibalising old '64s!!) Thanks for replies re: MIDI data file format. Marcus Bointon, King's College London.
