From the project
This is an AY3-8910 / YM2149 based sound/audio/chipmusic card
This is a AY3-8910 / YM2149 based sound/audio/chipmusic card designed originally for the LiNC80 SBC1 microcomputer, but should be usable on compatible Z50Bus systems, and also other Z80-based systems with a suitable bus adapter.
The design of this card is based on an early prototype made by Jon Langseth, adapted to the Z50Bus. The main "invention" is the address decode/glue logic, the rest of the circuit is a fairly standard implementation of an AY3-8910 circuit for the Z80. Some inspiration in the analog section comes from the "Simple AY interface" from hw.speccy.cz, as well as the ZX…
