Labor Day weekend, I found this empty PP cockpit (with pedals and CP) for $80 down in Cinci, so made a road trip to pick it up and hang out with some old friends for the night. I was really surpried how geeked my daughter was over this....I was not suprised how much my wife was not, but she went along with it.

I had planned to slowly piece it together over time, but on the drive back to MI, another fully populated cockpit project with PP2 board and extra CP/pedals popped up in Cleveland for $500. Took a quick 2-hour detour to make that grab but couldn't fit both cabinets in the truck. The cab already in the truck was the better of the two, and the seller was nice enough to help me strip his cabinet for the same price!

I called this a "refurb" because I'm not going all out on the cosmetics that I see in other threads. Someday I might circle back with more ambition, but right now, I'm just going to patch the chunks missing along the base and primer it (not unlike my first car).

The guy I bought the hardware from said he had tested the PP2 in his upright, but have picked up the cabinet from a friend and was not sure what did or did not work. $500 for a complete set of hardware plus an extra set of pedals and CP seemed reasonable, especially when I was looking at everythng there and realizing how long it would take me to find everything piece by piece.

Since I already had everythig out of the cabinet, I set it up on my bench yesterday to see where I was starting.

I had pretty much everything connected except the CP. I checked the power supplies before plugging in everything else and had 5.35V on each. So after checking to make sure everything was stable, connected, and no chance of shorting against something, I turned it on to see this. No smoke and the monitor works! But work to do....

Going back to the power supplies, I found that one of them was pulled down to 800mV under load. I was hoping it was a bad pass transistor and not the board pulling a ton of current. So I changed the 2n3055 and voila!


Progress! I wasn't sure what to do next, then I realized in the top right "ROM 8". I pulled that ROM and the game booted! Everything was great for 3-4 minutes, then the picture started to bend along the left side of the screen. I'm new at this, so I'm not sure if that is what is called "curl" or something else. A quick search make it clear that people don't have much good to say about the Matsushita TM-202G. I wasn't sure if this might be a cap thing or possibly one of the drive transistors flaking out after it heats up. The quick searches seemed to point toward caps, but still need to dig.


The other problem I had was no audio. I had hooked up the panel of volume knobs from the cabinet and they were pretty cruddy, so I swapped it for the one I stripped from the other cabinet, and that fixed it.

Once I get on top of this monitor problem, I'll post progress on the cabinet.
