I worked on the game this weekend. It started out with just numbers an letters that would stay that way. Know I got it so that it looks like mame starting the game up. zeros, the all kinds of characters with a guy in the picture and RAM ok, Rom OK then a green ground, then it starts all over again.
I have a new Z80, changed the CPU board with a backup that I had for pole position (had to add two sockets). I have a pole position game PCB that works 100% an the AR boards and power prick has been rebuild 2 months ago so that is 100%. all voltages look correct.
Any thoughts on how to fix this?
