Thanks!

Interesting...  It says SEP 1989...  Most of the diagrams in my
copy of the tech manual say "12-03-90".  Interestingly, exactly the same
page (without the "C6") is in version 2.3 of the manual.

Page C5 should be "Screen Mode 4" and C7 should be "SAM Coupe Keyboard
Matrix".  Is that right?

The content's completely different to what I was expecting.  I guess the
manual just wasn't very clear.  So I should probably explain things:

To find the keycode for a particular key, after having found its "switch
number" in page C8:

Look at the diagram on page C7, and find the entry in the table that
matches the key's switch number.  With the "Lower Membrane Connector"
(address-line bits) label on the left, and the "Upper Membrane
Connector" (output bits) label at the bottom:

Let x be the column number for the key in question, starting at 0, on
the left.  Let y be the row number for the key, starting with 0 at the
top.  The keycode is (x * 9) + y.  Add 70 if Shift is pressed, 140 for
Symbol, or 210 for Cntrl.

The values in the table match the diagram on page C8, but otherwise,
they appear to have no significance.

Well, I hope someone finds that useful. :-)
