Nothing should have that many legs

The gross bracket situation put a stop to any work on Mr. Do, but I still had the G07 to drop into Centipede. That one went in easy since the cab is as it came from the factory and the Atari engineers actually gave a damn about ease of service. I brought the machine up and the monitor showed nice picture. Unfortunately, it was a picture of total garbage.

I cleaned up the PCB edge connector with some Deoxit and removed all kinds of grossness there. Still nothing. Reseating the ROMs on the PCB was next. That got some results!

Still need to adjust the monitor a bit and do a proper rebuild of the trackball. I cleaned it up a lot but the rollers and bearings were neglected long enough to have rusted and the movement is quite rough.

Said to be playable with that crust on the rollers. Must have been a way tougher game that way!

They’re coming out of the walls!

Went out on Friday to go pick up some working monitors I’d heard were available since I have a feeling the repairs on the ones I have are going to take a while. The price was good enough I took the whole group.

One is a G07, another is a K4600 variant, but the third is kind of an oddball.

I’ve never seen one of these before. Chassis board is labeled Videomaster13 and the tube is a Samsung unit.

I also noticed the interface board for the K4600 I just got is different from the one on the K4600 in the Mr. Do machine.

Still need to research what the difference is (I know they take different sync signals at the very least).

I was going to swap the new to me K4600 into Mr. Do but then found that it had the shittiest brackets ever installed when it was converted. Two pieces of angle stock with four bolts… No support for the rear of the chassis or anything for the monitor to rest on when it is unbolted. Definitely a two person job to remove.

Also found this when I was having a closer look at the interior of the cab. Original Game Plan Inc. tag for Megatack.

Coin mechanisms and rules placards for Frogger came in on Thursday. Came from a game that was being converted to a MAME setup and sounds like it had already been butchered pretty badly.

Was really happy to see these come up, since this type of coin mechanism is kinda rare. They’re Conlux N500 units, and I’ve only ever heard of them being in 80s Sega machines.

The placards weren’t advertised but I asked if there were any other parts from the game available and got them for a few bucks more. Hoping to snag some joysticks as well since the second player stick is kinda sloppy on this machine.
