			Brought this off ebay 12mths ago and almost got burnt on the deal but that's another story. Hooked it up and got nothing but a blank screen.

			The board layout was identical to the sega frogger schematics so I used this for reference. I hooked up my sega board and made note of the control pins on the cpu. For memory there were 3 pins, BUSAK, BUSREQ and WAIT that were different.

			WAIT was held high instead of high low pulsing so I started here. Traced Wait back to a 74ls161 at IC82 which has pulsing inputs but no outputs. Piggybacked a 74LS161 and turned it on, still didn't have a picture but the outputs were pulsing now and I saw a small horizontal flicker of video so I cut the 161 out and soldered in another and it now lives.
