Will the Macintosh Plus M0110A keyboard work on a Mac128K?

Recommended Posts

I haven't actually tried this, but I'm sure it will work -- the only question would be if you were using a very early version of the OS from before that version of the keyboard existed. I'm not sure about the numpad/arrows in that case.

100% will work fine; note Apple offered an additional external numeric keypad for the 128K style keyboard.

Correct. The arrow keys and some of the other keys which the Plus keyboard added are dependent on System file support. As long as you're using System file version 3.0 or later (1986), you should be fine.

 

You can also copy the appropriate INIT resources from a newer System file into an older System file, if need be.

That’s interesting @Dog Cow.  I trust you, recall similar things (arrow key support in TextEdit wasn’t documented until Inside Macintosh Volume IV, for example) and haven’t tried mine with older System Software, but ... the numeric keypad available with the 128k Mac in 1984 had arrow keys.  Did they not do anything?  Or require dedicated application support through GetKeys() or similar?

Those technically weren't arrow keys, and instead Apple called them "field motion keys." They work in Microsoft Multiplan and probably other spreadsheet applications. See Inside Macintosh, volume 1, page I-36.

 

By the way, the Macintosh can tell whether a keypress came from the main keyboard or from the keypad, even if it's a key which is common to both.
