[net.micro] TRS80 keyboards

I agree with John Wavrik's comments on the TRS-80 keyboard; the early ones
were subject to terrible keybounce, but the later ones are among the best
keyboards I've ever used.  The entire keyboard is software defined, so you
can detect any key or combination of keys quickly and easily under software.
The result is that all the better operating systems for the 80 (e.g. LDOS,
NEWDOS...) have sophisticated keyboard routines.  LDOS supports N-key rollover,
autorepeat, and full typeahead.  (The only other "cheap" micro I know of that
has typeahead is the IBM PC, and it uses a processor in the keyboard to do it).
LDOS also lets you generate *any* ascii character from the keyboard, along
with a generous set of additional codes for controlling special functions.
The keyboard "feel" is excellent (though it tends to be a bit quiet for my
taste; I like auditory feedback as well as tactile).  (Note that I'm again
referring to the later keyboards; the early ones were extremely cheap and
felt awful).  The later keyboards also have a full numeric keypad, which is
some else you find missing in a lot of low-end micros.
