[sdiy] Practical Elecronics "Minisonic2"

[Julian Bunn]

Thanks ... I think I was fortunate with the keyboard. It turned
out to be exactly what I needed, although the original design used
dual pole keyswitches made by Kimber-Allen. I'm not sure if they
are still in business or not.

I was surprised I couldn't find anywhere on the Web which sold
bare keyboard assemblies. There must be such places, of course.

Julian
