(1 customer review)

$32.00 USD

The BackSID is now back in production! A small quantity are available right away, and backorders should be filled in 2-4 weeks.

The 6581/8580 SID is very fragile and can be damaged easily. They are also very expensive on the open market. BackSID replaces the essential functionality of the SID, offering a faithful reproduction.

    This is an awesome chip. It’s the only one I’ve seen that sounds great, is cheap, and offers potentiometer inputs. Unfortunately I need three more and they’re not in stock as of 9/22
