i can not get the board to run at all it is stuck in a reset
if i tie the hault and reset high i still can not get the 9010 to go past the first address
something is sending a rest pulsing and the screen just flashes with garbage lines on it
i pulled all roms and checked them in a programmer
and tried swaping out the proms with ones on a known good board
also swapped the cpu board with a know good one so i know the problem is in the cpu board
and the video board is good
i tried to bug trap all ttl 7400's in the reset circuit and replace any thing i found bad some 74ls116's
is this a ram problem ?
i am using a afterburner schematic i can not find the outrun one the cpu 1 should be on the outside right ?
how can i get the fluke to run to get this fixed
thanks
tony
