### Current status
Work in progress, both pcb and firmware isn't finished yet and may contain serious issues.
Please note the [errata](pcb/rev.A/ERRATA.txt) for rev.A pcb.
### SID
MOS-6581 or MOS-8580 may be installed, but with some cautions. This addon doesn't contain buffers between SID and bus connector, and that may cause SID's damage by ESD if no luck. As I have no real SID, I've checked this addon only with SwinSID.

Quiet sound output from nanoSwinSID.
Incorrect A8 and A10 signal connections on ZXBUS connector. A8 should be connected to pin B26 and A10 to B27 to get SID working.
