I have a Joker Poker . I rebuilt the power supply and did ground mods, replaced all caps. I replaced all connector pins to the boards and game has run at least eight years no issue.
As long as spider chips are good and you replace whats needed there should be no issues with the board set.
Pascal board looks great but i would only go that route if spider chips were toast. Or I really wanted features like skill shot. You can make original boards very reliable, connectors would have to be replaced regardless of which way you went, as they cause the problem. Or if someone wrecked gold contacts.
