Original SID chips are often semi-broken as well. I had a few when they were cheaper and I was building a midibox SID. Most had weird VCA issues or oscillators leaking to the output always. Stuff like that. If you end up with a half decent one the oddities just become part of the charm.
- city41 7y agoThere were two variants of the SID. The early one ran on 12v and the latter on 5v. As I understand it, the reduction in voltage greatly improved their reliability.
- exDM69 7y agoMore than just the voltage, the 8581 had significantly revised circuitry and better opamps due because they had much more silicon area and a better process available. It sounds disnctively different too.
