Centipede monitor repair part 2

Brand new HR6020 fitted, lets hope this is the end of it. Fingers crossed for a spark free powerup

MTC900E on the repair bench

Just finishing off a major repair

Pole Position - Ready for Replay

PCB fixed, power brick rebuilt, AR2s bullet proofed, extra 5v lines and commoned ground lines, new locks, steering and shifter mech stripped and rebuilt, new marquee bulb, new Atari big blue, new dip switches, NVRAM highscore saving mod, new cardboard monitor bezel. Phew that was a lot of work!

New Pole Position Bezel

Made out of mounting board. Was damn tricky to make but it turned out nicer than I had hoped for :) The original was a complete mess and had been cut by a previous owner

More goodies from China

Paperboy has gone faulty.

Stuck on the mostly blank highscore table with the soundboard making random noises.

You fix one machine and another one breaks :(

Pole Position reliability upgrade for Replay

As some of you may know, Pole Position gets a bad reputation for a few reliability issues. As I want this machine to survive the show without a hitch, I have performed several upgrades which should significantly increase reliability.

Firstly, due to the complex nature of the large PCBs ,they are very power thirsty. Atari had to add 2 AR2 power supplies to cope with this. I have added common ground wires to both pcbs and both AR2s. Next I ran crimped wires from the 5volt test points on the PCBs directly to the power supplies. This reduces voltage drop significantly and will stop the harness getting hot and the edge connectors burning.

Next I rebuilt the main power brick, including replacing the main "Atari Big Blue" as well as the rectifier and any corroded wires or crimp terminals

Next job was to remove the leak prone battery and replace the unreliable CMOS RAM with an NVRAM after modifying the PCB to accept it.

Lastly, several sockets were relaced with new on the CPU board as these are prone to being flakey.

With any luck, this should now be one of the most reliable Pole Positions in a long time.

Coming to a Replay show near you :)

Red Ghost Neon Sign (pacman)

I never get bored of unboxing cool neon signs. I think I will bring this one to Replay to hang on the Jammaplus stand.

Another Super Hang-On PCB back from the dead

So that is a spare for me and a spare for Replay now :)

Mini webserver up and running

Arduino + Ethernet shield

Electronic goodies from the wonderful people of China

Mmmmmmm gadgetry

Message Display Fixed

Ready for the Jammaplus stand at Replay

Another Super Hang-On PCB fix

Had to fix another one after the last one decided to have a PCM chip failure after 2 hours on the bench

Super Hang-On PCB fixed

Thats number 1 for replay, now need a second for spare

Krispy F**king Kreme!
