My most sincere appologies - I looked very carefully at the 2000 manual for
info on how the keyboard is hooked up, but found none.  I should not have
assumed that the 500 manual had no such information.  

Thank you very much for the reply, especially in the face of my failing
to adequately RTFMs.

Well, I didn't get any acrid smoke, but I also didn't get to type with the 
2000 keyboard.  After several days of using a 500 without it's cover and
intermintently firing up the soldering iron, I think I've given up on the
whole deal.  

For anyone else who might be trying, here is what I have found DOESN'T work:

500 keyboard connector (viewed from front of machine)
1  2  3  4  5  6  7  8
----------------------
3  1     4     5          /* What I THINK Mr. Robbins said */
3  1     4  5             /* A goof based on what I thought Mr. Robbins said */
1  2  3  4  5             /* a bad guess */
Female 5-pin din connector (as numbered on RatShack cat no 274-005b)


Besides the fact that my class work (programming) is suffering way too
much from these lame attempts at hardware hacking, I guess that if
I want an external keyboard and/or room to put junk inside the machine
then I should buy a 2500 in order to help pay for Messrs. Haynie
and Robbins, et al to work on the neat new machines :-)

The main problem is that 1000+500 (my two Amigas) only = 1500.
