Rik- that looks good. I'm pretty sure it's the same pinout. On the front, could you tell me the colors of the 2 resistors below the skill switch? Those and the one to the left (which I can see) are switched in based on the skill setting and change the oscillator speed. Also, can you read the value of the capacitor under the TMS1100? Not the cylindrical electrolytic, but the disc cap between it and the chip? It probably says 47 on it. It also determines the clock speed. Thanks.
