I recently completed the FM circuit on my AX-370 (somehow similar to Wavy 70FD).
Any description for this project? I'm interested in it actually!
I did it myself, I will have to write up the items needed for the project and the rom files needed. I will do that later when I find the time. but the items you will need in general are:
- YM2413 chip
- 74LS30 chip (SMD, not through hole)
- Inductor with the value of 150uH 1/2W - 1W (that's what I used, someone may have better info about the watt range)
- Few resistors 1/4W
- Few different type of capacitors.
- Space in rom for either FMPAC rom data or MSX Music preferably with Basic Kun next to it but not important.
