I have a soft spot for a handful of system 1 games and PP is one of them...

Looking forward to all future updates.   ^^^

Awesome work you produce Mitch.

Thanks for sharing.

Today i decided to put the game together, and see if i could power this beast up and make her work, at least enough to see what other work i would have to do on her.

First thing i had to do was to check that the power supply worked. This power supply looks to have never had any work done on it.. very unusual me thinks!! it even still had the original main filter capacitor for the 5 volts (big blue one). When i powered it up (with no other boards plugged in of course), all voltages were there, except the -12volt. since it was only this voltage that was missing, i decided to use the Ni Wumph CPU to test the game, since this board doesnt need the -12volt output. The power supply will be fully rebuilt during the restore.

Next i had to repin some of the connectors that were obviously no good, ie corroded and/or broken pins, and as i powered up the boards and displays i found more and more! no surprise really considering the state of the rest of the game. One of the connectors was completely missing (last pic), the coin door switch connector, so once again i ratted thru my spare bits n pieces and luckily i had the correct connector housing. I then had to re-wire the connector with new pins... WITHOUT the proper game manual!! all i had to go off was my Buck Rogers coin door switch matrix, diagram, and some of the wire colours were different. so i had to trace the wires from the coin door switches, through the coin door connector (where the wires changed colour!!) and up to the switch diodes, using my multi meter as well checking for continuity between the switches and the diodes!! From the other side of the diodes the wire colours changed yet again! eventually i had the connector re-pinned and working, clocking up credits and games etc #*#

The sound board had been butchered a bit, and of course didnt work. the regulator section was working and had the 12 volts there to run the ICs, but i worked out the amplifier IC was dead. Rather that muck around, i grabbed another sound board from my stash of parts that i remembered was there, and used that instead. I'll repair the original board another day.

at this stage the game was mostly working, with the exception of a few display digits/segments (3rd pic). So i then replaced all obviously damaged pins to get the displays all working properly.

Also i had to re-pin the playfield switch matrix connector, as it had a LOT of broken pins (1st and 2nd pics) I ended replacing ALL of these pins in this connector.

The rest of the connector, as i said i only repaired what had to be to make the game work, but i intend on replacing ALL of the pins on all of the backbox connectors when i start the full restore of the game.

SHE WORKS #*# #*# played a few games on her this evening, had to fix/clean a few switches that were intermittent, flippers and one bumper switch. also a couple of the remo-trip coils that knock down the opposite drop target arent working, but they can be taken care of when i do the PF resto.

It'll be a RIPPER of a game when its done.. to be honest i could hardly remember what this game was like to play all those years ago.. but playing a few games today it kind of all came back to me pretty quick!! This one might even jump the resto que yet, ahead of Quickdraw!!

Great acquisition, and kudos for keeping this from the trash heap - looks like lots of work but it will be worth it - one of the better system 1 games. I know of one locally I'd like to get the owner to part with one of these days.
