| |
| - +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 have 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.

| 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 drives to $FF. Otherwise it is hi-z. 27 could either be a /CE or W/R.
