| 1 | Y2 or Y4 | 3.58 MHz (or 4 MHz) oscillator | 520-TCH357-X | Oscillator (either half-size/8-DIP or 5x7mm SMD) at desired PSG frequency. MIDIbox Genesis firmware will correct frequencies to match original VGM pitch. | | | 1 | Y2 or Y4 | 3.58 MHz (or 4 MHz) oscillator | 520-TCH357-X | Oscillator (either half-size/8-DIP or 5x7mm SMD) at desired PSG frequency.

| 3 | Q1, Q2, Q3 | 2N7000 or BS170 | 821-TSM2N7000KC821-T or 512-BS170 | Any small-signal N-channel MOSFET with the gate as the center pin; the board silkscreen is for 2N7000, if you use BS170 (as I did) mount them backwards to match the source and drain pins. | | | 3 | Q1, Q2, Q3 | 2N7000 or BS170 | 821-TSM2N7000KC821-T or 512-BS170 | Any small-signal N-channel MOSFET with the gate as the center pin; the board silkscreen is for 2N7000, if you use BS170 (as I did) mount them backwards to match the source and drain pins. | | ||
- | | - | J1, J2, J7, J10 | 0.1" stackable pin socket/headers | 782-A000086 | Pin sockets with long pins (from Arduino shields), for stacking the boards together. Buy in bulk and combine them for the appropriate sizes. Use a regular pin header for the lowest board in the stack; have each header mounted with the socket below the board and the pins sticking out the top. See this photo of the stack. | | + | | - | J1, J2, J7, J10 | 0.1" stackable pin socket/headers | 782-A000086 | Pin sockets with long pins (from Arduino shields), for stacking the boards together.
