Yes, you need a DAC. I bought a cine monitor main board on ebay, then I isolated the HV circuit (!) and connect the game PCB to the monitor pcb with a flat cable. Referring to Rip Off manual on my site: http://www.vernimark.com/arcade/archive/pdf/ripoff_manual.pdf page 77 (monitor schematic) X and Y signals of my scope are connected to the output of R109 and R209, just before amplification circuit: I supposed to see a clear image. With my ATARI pcbs I see a very clear image connecting probes directly to XY outputs... Please tell me if something I did was wrong ;-) vernimark ---------- Initial Header ----------- From : [email protected] To : [email protected] Cc : Date : Sun, 13 Feb 2005 20:03:56 EST Subject : Re: VECTOR: Cinematronics on a oscilloscope > I am confused.
