I have a working NBA Hangtime now - thanks to J1ng for a killer deal.
Now I have my original board I want to get working, for the experience as much as anything else.
I am very confident the board itself is good - I actually have two boards and after removing all the chips and battery from one and reinstalling in the second I have exactly the same start up problems - and swapping the power supply doesn't make a difference.
So what I am curious about is the order in which I might tackle re programming the chips to see if I can get this working.
I have the manual and can identify which are the game images, music/speech, program chips, etc.
So I guess I should pull a chip, read the contents using the Willem GQ-4X softwareand then use romident to compare it and identify which chips might be bad? Is this right?
