I need your help....
I'm very happy Superbreakout board works :) with the exception of sound but TDA1004 is missing on the PCB so..... I think it could be an easy fix ;)
anyway in this cab there is the original monitor, a Tec Videoelectronics inc. TM-600 Tv Monitor
manual here: http://www.vernimark.com/arcade/archive/monitor/mon_rc_tm-600.pdf
when I switch on the game screen is dark but after more or less one minute I can see the image rather faded.
It's a good start, yes, but no h or v sync and using both pots it's impossible to have a stable image.
signal is ok because I tested the game on another monitor, and power section is ok too because I have 100V on R907, as indicated into the schematics...
I'm quite confused I can't stop neither H or V, it seems somposite sync is not splitted correctly from the signal... any idea?
