I bought a non-working Joust off Craigslist yesterday for $100. When I picked the game up the power supply wasn't outputting +5V at all so the game wouldn't even attempt to boot. I got the game home, opened it up, and to my surprise discovered $35.25 in change!!!! So essentially I paid $64.75 for a non-working Joust. Not bad huh? After removing & reseating all the IC chips I found that the CPU chip and one 4116 RAM chip were seated backwards. Now the game boots up with the screen below. Measuring the voltages at the power supply I get +5.08V, -4.75V, & 11.84V. If I measure the voltages at a 4116 IC chip I get +4.79V, -4.75V, & 11.74V. Is this just a case of some bad RAM or is the problem larger? From the manual the voltages seem to be acceptable. Any advice would be appreciated.
