TheShanMan's Defender restoration - New repro wiring harnesses!!!
SirPeale:
How are you removing the ROMs? DO NOT use a chip puller. Use a jewelers screwdriver. Pry up on one end, then the other, walking the chips slowly up.
But I don't think you're having ROM issues.
Have you fired Defender up in Mame yet? Check the startup sequence. How does it compare to what you have?
TheShanMan:
Actually I WAS using a screwdriver, but I was thinking "I wonder where my chip puller is", so I'm glad you said that before I found it. :)
I don't think I'm having a ROM issue (yet) either. There is NO startup sequence. It just turns on to that yellow hash screen and that is all it does.
Kevin Mullins:
Clean and re-seat any socketed chips. (my $.02 on that part)
"dangling red wire"
Horizontal position jumper.
Connect to any of those three pins, whichever suits your needs.... Left , Center , Right.
SirPeale:
Oh, THAT wire. Sorry, didn't see it. Yes, follow Kevin's advice.
I'd like to see some video of what happens when you turn it on, if that's possible.
In this picture:
it looks like you're getting rug pattern.
TheShanMan:
Regarding the wire, I'll hook it up, but how would one decide which one to hook it to. It's not an arbitrary choice, is it?
Here's a better pic. I could try making a video but not sure what that would accomplish. All it would show is the screen showing this as soon as the monitor warms up. Let me know if this pic isn't adequate though.
And to bring attention to an old question again: is there no such thing as "rom 5"? I have 11 roms, numbered 1-12, with a hole at #5.
