I'd be interested in Space Duel and Asteroids Deluxe.

Thanks for the pictures. I took the board set out tonight. The reason I couldn't find the battery is because it was gone, and the wiring harness was covering up the blank spot on the board. This seems odd as when the game goes through it's attract mode, it still displays saved high scores...

I ended up with an Omega Race this weekend. The board is really clean, no acid damage. The monitor is a tiny bit blurry (focus adjustment?) but otherwise works well. As I understand, I could replace the board mounted battery with a 3.6V rechargeable phone batter. I'm assuming any old 3.6V...

Battlezone I don't think Space Invaders had a joystick, just left and right buttons.

I think that's even sketchier than the last time I moved a game.

I thought of that, or just leaving it on and not doing anything. But I'm some vague form of a purist, and brzezicki totally hooked me up. I figure if the button was included on the board, it must serve some purpose, perhaps in diagnostics.

These board sets could be used with old TV tubes? Do the tubes have any special requirements or size limitations? Any thoughts on what all the components will cost? I imagine you could put me down for two sets.

It drops off pretty fast, doesn't it? True that. I consider myself to have pretty good problem solving skills, I just don't know a whole lot about this sort of stuff yet. I'm pretty tired of crap tools and I want to make sure I buy some tools that will do the job well and last. If you have any...

I have a Battlezone PCB that has a frozen reset button. It's feels like it has some sort of corrosion on it that seems to be preventing movement of the button. My thought is to remove it, soak in acetone, check to see if it still works. Anybody know if these buttons are normally open or normally...

Is there a logic probe/oscope that would be recommended? I already have, what I like to think is a pretty adequate soldering station. I think it's a WES51, but I'd have to check to be sure. I've read good things on this forum about the Hakko 808 desoldering station, and from recent experience I...

I'm going to guess 37.

Looks like these are all sold out?

Sounds like we're starting to get a little bit beyond my abilities. I don't even have a reasonable digital multimeter. Is this something I could do a little reading on and figure out, assuming I become better equipped?

From what I can ascertain from my forum search, the BIP pots are used in self test mode to try and match the extents of the diagonal lines with the solid border? I can make everything move around using the pots, but alignment doesn't occur within the range of the pots. Maybe board caps need to...

Thanks for the help. I installed an IC socket at B1, took RAM 2114 from my Asteroids ran it in the Battlezone. No change that I can see in the game graphics, but when I run self test, I only get one low beep, and the test provides a visual (just had a blank screen during self test before). The...
