Ok, I think I can take some readings.

Shutdown time ? So if the -5v line is dropping out this would mean exactly what ? I'm a newbie and need things spelled out. LOL thanks

Here's an update. I pulled out the game and took out the boards to have a look. I couldn't see anything suspect so I reinserted them after cleaning the conectors. Now it will come on and I can play but after about 5 min or so it stops and goes back to the grid screen again. Bummer, I thought it would be easy. I 'll take them out again and reflow the solder and if I have to swap the boards. What do ya think ? Oh and any more info on the reset error would help. thanks

Thanks for the replies guys. Crazy, I'll let you know, thanks. Yes, these were the ones in Wilmington. The seller said he got the one working sort of. He swapped boards but the monitor took 20 min to "warm up" and then he said it was blurry.

Wow ! Thanks a bunch Cassidy. I'll start by cleaning up the cabs swap pedals, plastic, etc.. I'll also check on that monitor.

I just picked up three of these the other day. Between all three, I should be able to get one to work. I have extra boards, monitor, and other pieces for them. I have never put one together before so I may need to ask for assistance. Like, where do I start ? LOL

They should be drawn and "quartered".

I wish I still had my TRS-80 Model 3, I could use the processer from there. LOL

try looking at your connector first. then at the connector from main pcb to daughter card. if you run into a dead end there try swapping out just the z80 chip. if that still doesent work then you probably have a reset circuit error. please post your findings. I have the same game and have had simular problems. I got past the grid problem but then about 6 months later the board went dead again and I haven't torn in to it again I'll give it a go. Is that how you fixed yours, by swapping the chip ? What is this " reset circuit error " ? Sounds like a power problem of sorts.

I bet it fell off the back of a truck. Your dad seems cool to me. LOL

Are they storing it there for a raffle ?

Now that my Asteroids is up and running I'm going to try and get my SID working. The game powers up to the attract mode and then immediately a grid of squares appears in the middle where the title was. It then just refreshes this grid forever. When I got the game it worked for a few days before this happened. I have a untested pcb and daughter card for it I will swap but thought there might be a easy fix first. Not saying that swapping pcbs isn't easy, just a waste if I can get the old one working.

WOW That's some improvement. It looks like a vinyl overlay.

I think I'll get one. I'd also like to fix up the paint on the control pannel, any suggestions ?

Do you use the preassembled boardset like the ones for sale ?
