But the fact is that the M5140 cannot be the "first AC adapter" for Apple portables, since the first Apple portable was not the PowerBook 100. The first portable was the Macintosh Portable. But what is the model number for the Macintosh Portable's AC adapter?

Also, it is said that the PowerBook 100's AC Adapter works to boot the Macintosh Portable even if the Portable's battery is dead. However, does anyone know if that adapter is the original model M5140 or the replacement adapter, model M4662 (or both)?

And what would happen if the M5652 were connected to the Macintosh Portable? Would it fry the board? Apple's article says the M5652 would damage the PowerBook 100.
