UK location preferable. I'm looking for tested and 100% working unit - R3 only. Cheers.
 
hi,
look this:
6581 R3 - Will say "6581" only, "6581 R3" or "6581 CBM" on the package. Had a minor change to the protection/buffering of the input pins. No changes were made to the filter section. Made from before 2083 until 1386 or so.
(from: http://en.wikipedia.org/wiki/MOS_Technology_SID )

So do you search a SID only if it is marked "6581R3" or it can be "6581CBM" or 6581 from 2083 to 1386?
