Only if someone buys the game without it first.

Exactly!

I do not. But can remove the LCD and take off $100. Let's make a deal!

Price drop to $750

Location: Naperville, IL 60563 Really nice shape. No water damage. Monitor was replaced with a Happ Vision Pro arcade LCD screen. Pick up near Naperville North high school. Will consider trades for pinball machines.

Location: Naperville, IL 60563 Plays great. Trackball and buttons work well. Sound is now going in and out. Has some cabinet swelling on bottom left side. Moved to garage for easy loading. Will consider trades for pinball machines. Asking $1,250 obo

Someone called the seller and told them it's at least worth $1,500-$2,000, so he kept relisting it. I did not pay that though. The bottom left side and bottom of the cab have water damage, that's why it's strapped together.

Picked up a 1976 Midway Sea Wolf. Was working great, then I moved it. It now half works…when turned on, monitor flashes white with the screen image…then no more image. Same thing when turned off. I can hear sounds and I can see the 4 torpedo lights when looking in the periscope when a game is...

I can’t find the datasheet for this IC chip. Safe to say I can just match up the pin #’s based on where the IC notch orientation is? (I’ll also try and check a few traces visually)

@tendril - thanks for the tip and for taking the time to call out 34n and 31n as examples. Both 34n and 31n are socketed chips. I'll take them out and clean off the legs and reseat. Continuity is something I can check. Thanks!

Hello, My 31s and 34s chips are coming up "bad" in the boot up sequence. Anyone able to burn me two new chips? (42-pin) I'm in the Chicago area. Thanks!

Here are the two chips that are suspect, but a Google search turns up no info about these 42-pin chips. Anyone here able to burn two new chips for me?

Is Badbaud Alan at K-Lar? If so, I spoke with him on the phone yesterday and he actually throws these chassis’s away and replaces them with a Ceronix tube and chassis. I could find all but one resistor (R146, that connects to the deflection yoke 4-pin plug) on the schematic. I don’t see any...

Digging in, realized the chassis board is missing 5 resistors and a capacitor. The HOT tested fine out of circuit, but the B+ transistor was shorted. Given the lack of knowledge on this specific chassis, I'll either try and find a tube/chassis to swap in or move it on as a project. I also...

Thanks!
