So I did do a board search and didn't see anything. (and I will look some more)
To Sum it up.
I have a guy in a different state who is trying to fix a Gorf. I have a boardset. (and he sent me photos)
He said he had someone work on it and say that U15 was bad and was unavailable. (which I don't believe)
So board #1 (one with connectors) has a U15 (J4LS161) (if I remember right from 30 yrs ago it's a memory chip)
Board #2 - no U15 but others starting with U and X (Original ROM Board / Eproms on some peoples boards that have been copied)
Board #3 (pattern board) has a U15 (MC14013B)
Board #4 (CPU Board) U15 is the 40 pin AMI Chip (C2860D1) - I'm assuming from my old troubleshooting days that if this one is
bad, that the game would not even boot / power up and play. (Only socketed chip in the bunch)
Board #5 U15 is MK4015N (all chips are the same
Board #6 U15 is ITT 8117 - second line is 4027 4N (which is usually the date code and I don't believe it applies)
If you got any opinions (don't spend a lot of time).....I'm in the process of booting up my old windows 95, 98 and Win 2K computers and
looking through my old game technical notes and I think I have a manual both paper copy and electronic. (I'm getting there)
If you think it's a monitor issue, that's possible too and now I see I'm on the monitor thread - which is probably incorrect - sorry.
Thanks - (from an old school tech who "lived the dream" on games in the 80s
(sure wish I could find my notebooks but my memory is still 80 or 90 % there )
I've attached photos and he said he has a video if needed. (selected thumbnail - if I need full image I'll repost)
