I'd live in Spy Hunter, because it's always broken so I'd get plenty of sweet sweet ratty rest

Got the supply working after finding some of the pins in the wiring harness were in the wrong location  Shocked

Now I'm down to RAM errors on the board. most likely due to +5v voltage drop. Going to reflow headers on the MPU and try the 5k pot voltage hack on the power board so I can actually adjust the output volts and get a good 5.1v to the RAM

OK, my first real post here, let's see if it's a good one.

Bought a working Joust for my wife, got it home, it played for 45 mins and then the power supply went poof, not entirely surprising as it had been in storage for 2 years and doesn't look like it has been looked after very well.

I was getting LED #2 and #3 lit on the power board but not #1 for the +5V.

Bought a Bob Roberts deluxe Williams PS rebuild kit and replaced everything including re-pinned connectors and both transistors on the heat sink except for the header pins, only because I don't have a de-soldering system meaty enough to get them off.

Now on power up I get LED #1 and +5V at the ROM board with a 1.3.1 error but I don't have LED #2 or #3 lit. All fuses are new. Haven't spent much more time on it than that so far. WOndering what to test next.

Anyone know where the big bowl of Dick soup is? I looked over by the hors d'oeuvres but didn't see anything.

I can smell it so I know it's around here somewhere.  ;)

Hi All,

I have an empty Williams Blaster cabinet in really nice condition and I would like to restore it to a fully functional cab.

I am attempting to source the boards from the original machines as I really want to do a faithful restore, no Jamma or multi williams stuff.

I already have a sound board and know where I can get the interface board, I wondered if anyone could advise me on where to look and who to talk to in my efforts to track down the CPU/Video, Power and ROM boards for this game.

obviously I know there is eBay, Craigslist and the Arcade-Museum forums, just wondering who/what else is out there that can point me in the right direction.

Many thanks

Joel
