SID-goodness just keeps on coming. Some while ago Tomi Malinen released his DualSID twin-SID PCB. Depending on how the board is assembled and configured you can add either SID model to any C64 model. Additionally, the second SID address can be configured using jumpers. With DualSID board you can have both SID models in one C64 or configure yourself a stereo SID setup for any twin SID application. Anything goes. It’s probably the best and most versatile PCB design so far for adding another SID chip into C64.
I ordered myself few kits already a good while ago, but I have been lazy with my C64 activities lately and have not yet assembled them. I will have to come back to this topic once I have assembled and installed one.
Meanwhile if you’re interested for such board get familiar with the DualSID web site.
Here’s a picture of the kits I ordered:
Three DualSID boards and components for one 6581 and one 8580 model. While the board is the same there are different ways to assemble it depending on which SID model you are going to have as the second one. The FAQ on the site will help to understand the possibilities, limitations and why there are two different ways to assemble the boards.
Also, HVSC update 54 is out!
