According to the wiring diagram in the manual, the 24-pin edge connector (video) is:
A: video ground
B: red
C: green
D: blue
F: comp sync
H: v sync
K: h sync
However, the PCB itself is numbered on component side (actually pin 1A is identified and 12A)...looking at the backside (solder side) it looks as though several pins run together/are not intended for use.
Add to this the confusing numbering/lettering imprinted on the actual edge connector (holding the connector so the solder eyelets are facing me, the numbers increment down the right, and the letters increment on the left....so "A" on the connector would be "1" (or rather 1A) on the PCB...
So does the wiring diagram (on paper) match the lettering on the connector...or the numbers printed on the PCB (parts-side)?
