Description
Have a faulty 6581/8580 SID chip and need a replacement? The Nano SwinSIDb is a great choice (though I will admit, not best), but it has one fatal flaw: lack of paddle support. Using this revision on the original Nano SwinSIDb design, you can “piggyback” your original SID chip with a faulty audio circuit and use some of it’s secondary functions to add back in support for reading analog paddle inputs, external audio input, and random number generator while synthesizing music using the tried-and-true nano SwinSIDb circuit and firmware.
If you don’t have a faulty SID chip with working paddle inputs, you can still grab this board to restore your Commodore’s voice! Maybe someday you can pick up a faulty SID chip for cheap online to pair with it…
For more information or if you’d like to make this open hardware kit yourself, check out the project on Github and the original article that the hack was based on. If you’d like to learn more about the nano SwinSIDb, check out this tutorial by tolaemon.
Notes:
- Does not include MOS6581/8580! Also, not necessary for this product to be operational.
- These boards have all been hand-built and tested by yours truly. If you encounter any issues, I’d be happy to help diagnose them with you.
- These chips will come preloaded with the ‘Lazy’ fix firmware by CodeKiller.
- The ICSP port is flipped backwards on v1.0 of this board. If you decide to update the firmware on this board, double check the power and ground pins on the 2×6 header before attempting to program it.
- There is plenty of clearance in my SX-64 for both the SwinSID and a SID chip with a tall heatsink, but a breadbin 64 may have some trouble depending on your heatsink.
- If you have any questions or any issues with this product, please contact me and I’ll see how I can help you and even improve the product.
