Mini-Wave/Wave City Expander boards
2004-02-20 by grantrichter2001
Dave Hylander is doing another batch of expander boards. These are usable with the Waveform City and Mini-Wave. Adds sockets for 10 PROMs for 2,560 waveforms. You could probably run the encoder out the back above the power connector. http://www.hylander.com/miniwave.html
