MOS Technology SID
The MOS Technology 6581/8580 or SID (Sound Interface Device) is the built-in Programmable Sound Generator chip used in the Commodore 64 and Commodore 128 home computers in the 1980s.[1]
Development
The SID was devised by engineer Robert "Bob" Yannes, who later co-founded the Ensoniq Corporation.[1]
Caveat emptor
Since 6581 and 8580 SID ICs are no longer produced, they have become highly sought after. In late 2007, various defective remarked SIDs started appearing on eBay as supposedly "new" chips. All of these remarked SIDs have a defective filter, but some also have defective channels/noise generators, and some are completely dead.[2]
