Subject: Composite_colour_mod_for_Master_128

Apologies if this has been covered before.

I found a doc that indicates how to do the composite colour modification
for a Master 128, which I want to complete. It states 2 methods for 2 different
issue boards.

Issue 1 Board - 470pF cap (assume a ceramic cap is okay) across east leg
of R137 and east leg of R153.
Issue 2 Board - Link LK11

A few quick questions, I hope somebody may be able to help with.

a) what is the easiest way of working out which issue board I have (I found
some marking like "ISS.1", I'm guessing this means Issue 1 board?
b) The resistors cover the Rxxx markings, making it difficult to locate the
correct ones to solder to. I haven't been able to locate a board layout diagram.
Could someone point out which are the two correct resistors to solder the
cap across?
c) *IF* I have an issue 2 board, where is LK11? I did a manual search across
the board, but I couldn't find it (probably looking straight over it knowing
my luck!!)

Thank you for the assistance.

Steve.
