Some time ago I reconfigured the keyboard layout to use a character 
set (ECMA 8-bit standard) that combines latin and greek within the
same 8-bit code set.  Given this set, I wanted a normal greek typewriter
layout, with latin accessible via the option key (or vice-versa).

I found the keyboard maps in system ressource INIT0  (INIT1 for the
number pad).  If you open INIT0 with resedit and browse through the
data, you come accross a series of codes starting with 61 73 64 66...
(71 73 64 66... for a french keyboard) corresponding to keys a s d f...
These codes are in the order of the key numbers in IM vol I-250 and
IV-250.

If your system was configured for the US, there should be 6 such series,
one each for:
	normal (lower-case)
	SHIFT
	SHIFT-LOCK
	OPTION
	OPTION-SHIFT
	OPTION-SHIFT-LOCK
If your system was configured for another country or reconfigured
using "localizer", you will find a total of 12 series.  The extra
6 are for the "international" keyboard (one extra key) that used to
be available for the 128 and 512.

The keyboard routine is actually more than just a lookup, because
for a few characters (diacriticals) the routine waits for the next 
character and eventually substitutes a compound character.  That
is defined elsewhere in INIT0, and occurs as far as I could tell 
after the initial mapping.  The Keyboard DA reflects, as it should,
the final result of the mapping.

For the greek layout, I just pasted new values into INIT0 
using resedit.  To make things nice and general, I even cannibalized
Localizer (calling it "Greekalizer") to swap a greek keyboard into any
system for any Mac for any country.  Along came the SE with it's new
KMAP and KCHR ressources and messed my efforts up...

It seems that with systems 4.0 up the system can look in three places
for the keyboard layout, so you have to modify all three for a 
"universal" fix.  Occasionally, it slips at start-up and you get
the wrong layout.


This information is based on guesses and trial.  Please correct me
where I'm wrong.  I'd appreciate the same info for SE and IIs (ie: 
where is that darn table).  Also, does anyone have an opinion on
a DA (?) called "MacKeymeleon" that  reconfigures keyboards?
