Well, let me try again...

The keyboard clock does work, but not with the 6301v1.0  (which is rev. 1).
That is the chip of the early 520STs sold (of which I have one).  The good
news is that the mod works perfectly with the new 520 and 1040 which have the
rev 2.0 chip.  The keyboard part number that works is C070240-011.  If you
have one of the older keyboards, I don't think you can use the mod (I tried
for over two days to get it to work -- I wish someone would tell me what the
difference between the revs is!!!!!!).
I am getting together a little doc to send over the network which could be
followed by a layman (not a schematic alone -- hopefully I can draw a board
with the character set)
Anyway, if someone at Atari is listening, please tell me what the difference
in the two chips are.  I have been on Compuserve in the developer's sig, and
there are no documents which explain the difference, not even the new
hardware manual.
I could contact the company that makes the chip, but that would be a hassle.
