- Anybody have any idea how I would go about buying some chips from a place
- in England? I found something on the net that would be perfect for a musical
- toy I want to build. It's a keyboard (i.e. synthesizer) scanner that outputs
- serial data according to MIDI (the synthesizer standard protocol) specs.
- Sounds like one needs to add a clock crystal and power, and the rest is in
- the chip. So what's the conversion from "pounds sterling" to US dollarinos?
- Better yet, if anybody has anyway to find out if such a chip is built and
- distributed in the US, that would be great.
