No Dell,
I can't tell the difference from looking at that picture. I doubt anyone in this forum can tell whether the Pro-4 photograph shows a 555 timer or a microcontroller. I don't see anything that looks like a microcontroller, and the IC in the photo looks like some 555 timers I have seen. In fact, this is why I asked.
What is the chip number for the microcontroller that you claim is in the Pro-4? Also what is the chip number for the computer, or is it the same microcontroller that looks like a 555 timer?
Best wishes,
