Hi Joe:

Thanks for peeking in your keyboard again -- it seems you may have the only
one out there.

    I opened up my keyboard and traced out the circuits
again today. I HOPE this is right, I haven't double checked it. Everything in
caps is as it
appears on the keyboard. Names that are too long are abbreviated and shown
in lower case. A list of the abbreviations and their meanings is also shown
below.
...

pin   	21	20	19   	18   	17   	16   	15   	14
2	nu	kl	K1	K2	K3	K4	^	da
3	1	2	3	4	5	6	7	8
4	Q	W	E	R	T	Y	U	I
5	A	S	D	F	G	H	J	K
6	sb	Z	X	C	V	B	N	M
13	nu	nu	-l	da	-CHAR	REP	->	<-
12	nu	RESET	bs	nu	=	-	0	9
11	nu	nu	nu	sca	)	(	P	O
10	nu	nu	nu	nu	el	'	;	L
9 	nu	nu	nu	RUN	PAUSE	?	>	<

Abbreviations:
nu = not used
da = down arrow (up and down arrow are used to recall previous commands and for
editing)(I just noticed that I have this listed twice so there's
probably an error there somewhere).
...
 k1 = Key Label
el = End Line (this is what HP uses for carriage return/Enter)
sb = space bar
bs = Back Space
-l = -Line (erases the entire line)
sca = Scratch (erases all memory, just variables, etc depoending on what argument
you give it)
...

Notes: The K keys are programable function keys. K5 through K8 are K1 through K4
shifted. You can assign programs or functions to these keys and
use the Control input lines to trigger the program or function.
...
 The -Char key erases one character at a time.
the REP key toggles between the insert and replace modes.

   There are a few more keys that don't fit into a matrix. Here's a list of
them and the two pins that they connect to:
...

  Both SHIFT keys are tied together in parallel and connct to pins 18 and 7.
  There is a 8 Ohm .2Watt speaker inside. It connects to pins 25 and 7.
  CNTL key connects to pins 23 and 7.
  CAPS LOCK key connects to pins 24 and 7.

   I'll try to photograph the keyboard and post the picture tomorrow so that you
can see what the layout and key legends and shifted legends are.
