On my max it’s the delete key to get into BIOS

I still have mine and sometimes bring it to the Northwest Pinball and Arcade Show but not recently. According to the numbers sheets that was recovered 1900 were made, seems like a decent amount for a 70s title. Not one I see to often and on a side note for some reason a lot of the PCBs have...

PCB: Atari Tank Symptoms: Burnt power traces, missing 8000uf cap on board II, Missing 14 MHZ crystal After installing missing components there was no image on screen. Later I found the white tank not firing black tank makes checkerboard over whole screen when firing., black tank graphics...

I can take look at you tank board if you like I’ve worked on a few over the years as well as the repair I’ve had to do on my boards. The power supply is part of the PCB for the most part with the exception of the multi-tap transformer and there not mush to fix on that. Send my a message if it’s...

What transistors are being used on the board to trigger the lights. I've noticed some delay the light more then others even though they say they are equivalent. I stick with 4401 and 4403s

I’d take a look at your noise gen circuit. It’s the 4030 and 4006 at N5 and P5. It gets added and helps create the missile sound

are you seeing change in the outputs on L5 (74174)? It interacts with the car image and lodading of the motion for the cars. I’d try that first then if it looks okay check the outputs of the 9301s at k8 and p7 to see tif the load signals are there. That’s my guess on what may be wrong.

Yeah it was Hustle we played, happy to hear you liked it. It is a 1 or 2 Player game but It’s more fun with 2. Mine isn’t an original Hustle cabinet it’s a Blockade with a Hustle marquee and board. We still need to play a couple rounds of Tank. I didn’t get to show you guys how it plays after...

It does look like the scrolling could be an issue with the vertical motion. I’d start by checking the counters at J7 k7 and L7. Those 9316/74161 are problematic and it wouldn’t surprise me. You can test the outputs and see if they are pulsing. The service manual also seems to go over further...

My control panel has taller black plastic buttons like Brick Top

Here's what I found for Tankers. I think it shares a lot with Bi plane if I remember correctly. You may want to look up that for pinout

I've only came across 1 Rev C PCB while I was working on them They do seem to be pretty rare. I've never seen an A or B rev. I took pictures of it since I hadn't seen one before. It did use S4 for CE. These pics are all I have since I had to return it after I got it working. I'll try and attach...

I thought I should add that the XL had 2 different motherboards Telco and DeAmertek. Telco supports the Titanium image as is but if you have the DeAmertek and previously running older software you will probably need the VRAM upgrade too.

There is a diode that can cause no sound if it is bad and I believe you can test it on the board. It the 1n4004 closet to the 1000mf cap. Well that’s the most common part I seen go bad on the power supply that causes it. are you seeing the 14v give or take at pin 15 on the PS board? How about...

As others mentioned you can play a SI in a SID cab. The SID daughter board is also used for Space Invaders II, The one were you have two bases playing at the same time. SI II has a aux sound board and that third connector is where it plugs in.

the midway space invader schematics are labeled wrong on the versions I've seen the one labeled invaders hit is actually saucer hit and visa versa. so the 3900 you want to be looking at is k4 and k5 and the circuity around that. The 74175 at A5 controls the shifters I'm wondering if that's your...

It would be Qwak and Space Race for me. They just don’t seem to come up very often.

Lines in the moving objects should be a bad chip in the shifting circuit on the daughter board most commonly the 175s in row 6. If not the 153s would be the next to check but there are usually input issues too if they go bad. poor conductivity between the boards at the edge connect could cause...

You will need to remove the tantalum caps between the sockets too or one of the address lines will get pulled down. I can’t recall which on of the top of my head. You will need the address line if you move to 2716/2732.

I think sprint 2 would be a nice one or tank might benefit. It has a lot of chips that can fail ( cough 9316s) and the obsolete amps.
