  25229 : This also has the 40 pin ASIC but with a
totally different 
 layout. C1 is a 0.1uF cap Near the power connector. CR1 is a 1N4148 a few 
...
  components back from the middle of the front edge.
There are 2 zeners, 
 CR8 (12V) near the head connector and CR18 (2.4V) about halfway between 
 the front edge of the board and pin 1 of the 40 pin chip 
That's the one!  I suck at ASCII art so lets try text.  Looking
at the board component side towards me, 50 pin edge connector
up.  In the upper right corner is a tin can cap aligned veritically,
silk screen seems to be "C26".  To its left is the power connector.
Below it, aligned horizontally, is a clear component with bright
copper ends and fine black print which (straining my eyes) seems
to read:

104
 Z
50V

The silkscreen that seems to be associated with it is "C25".
Directly below that is where the missing component was,
also aligned horizontally.  The silkscreen that seems to be
associated with that position is "C1".  The leads that remianed
had the same bright copper ends still attached.  There were
bits of curshed clear material stuck to the board.
