[net.micro] apple ][ keyboards

Although I am not certain, I beleive that the APPLE ][e keyboard
is quite different than the apple ][ keyboard.  The apple ][ keyboard
is a simple, standard ascii keyboard that sends (as mentioned) a 7 bit
ascii character and a strobe line to the main board.  The ][e, on the
other hand, uses an unencoded keyboard, and has the keyboard encoder
on th main board (save money, you know).

The Apple IIe keyboard is indeed decoded on the motherboard, but not
just to save money.  One of the problems with the older keyboard
encoders was:  the keyboard, being at the top of the machine (no fan in
a standard Apple II. . .) would tend to get hot.  The keyboard encoder
chip would then either go intermittent, or fry completely (this was
mostly a problem with older revision, many-extra-board machines, but
just between you and me and the phase of the moon . . .)

I am not connected with Apple Computer Incorporated; I'm just a long-time
II+ owner (and Zenith Z-100 (hurrah)).
