What differs, by the numbers
2 of the compared properties differ. Counted from each edition's own definition, so this holds whether or not anyone has written the differences down.
| Property | Base | Base | Base | Base |
|---|---|---|---|---|
| Switches | 0 | 0 | 0 | 8 |
| Coils | 0 | 0 | 0 | 2 |
Counts come from each edition's own definition. A zero means the definition records none — for a stub or partial edition that may mean nobody has described it yet rather than that the machine lacks it.
