| Notes:
| |
| - +5Vcc pins 18, 59, 81, 100 are all connected together internally.
| |
| - GND pins 23, 29, 70, 90 are all connected together internally.
| |
| - 43, 44, 45, 46 are GND on the PCB, but have internal protection diodes from GND, suggesting they are logic pins.
| |
| - 24, 28, 36, 37, 41, 63 are n/c on the PCB, but have protection diodes from GND, suggesting they may have a function.
| |
| - Pins 41 and 42 ranges shown are duplicated at $Cxxx (i.e. ignores /ROMSEL).
| |
| - Pins 45-46, when pulled high, causes oscillation on pin 56.
| |
| - Pin 29 is a /reset. It sets pins 52-57 low when this pin is low, and possibly lots of other things.
| |
| - Pin 16 Pull-up of 20k to 5V is also required in order to avoid triggering reset.
| |
| - Pin 16 seems to be related to pin 29. With pin 29 floating and pin 16 pulled high at power on, the chip runs for 5 seconds, then enters reset.
| |
| - Tested 10k instead of 20k (per original PCB) on pin 16, found no difference in time or function.
| |
| - Pin 69 has a high pulse of 11.9085 usec at any time that register $4xAC has not been read for 12.4892 seconds.
| |
| - Each additional 12.4892 seconds generates another pulse.
| |
| - It has very repeatable precision, at least 6 figures on each.
| |
| - It is not synchronized to M2 or any other inputs.

| Notes:
| |
| - 6 & 28 are connected together internally.
| |
| - 17 has no measurable connection to 6 & 28.
| |
| - All logic pins have protection diode from pin 17, suggesting this is the true GND.
| |
| - Pin 25 also appears as a logic pin with respect to pin 17.
| |
| - When pins 25 and 27 are both driven low, the data bus becomes an output. Otherwise it is hi-z. 27 could either be a /CE or W/R.
