Me too. I severely undersold a low-number Mario Brothers widebody because everyone kept deleting the prices and the ones I found were several years old. Didn't realize the values had gone up so much! But I stood by it and sold it anyway for that price. It was the honorable thing to do.

She's on her way to delete!

Looking at the board now that it's out of the game, some of the solder joints on the connector pins look shady. I'm going to give them a tidy up and see if that does anything. Then I'll move on to the schematics.

Well, it's on the CPU. I swapped the Robotron Interface in and tried to ground inputs onboard using your schematic above. No activity on the test screen. I swapped in a known good early CPU and all the inputs worked using the cocktail's original Interface board. This is a cocktail, so the...

Yes the ribbon was replaced recently by me. I run coin, and yes there are credits. I also put it in freeplay just for the heck of it, but still wouldn't start. But I'm confirmed no switches working from the test. I also tried an early Interface board, but no action either. Although I did not...

I forgot that switch test was there. I've never actually had to use it before. I did ground out the pins on the interface to try and start a game that way but no response. I just ran that switch test and the only ones that respond are the ones directly from the CPU. The known good interface...

Game boots fine. Ram/ROM tests good. Goes into attract everything looks fine, but won't start. It's been running fine daily for 6 months or so, but it just stopped starting earlier this week. Swapped interface board with known good board. Still won't start. 4.8v on the interface and out at the...

Yech. Well you may have found part (or all) of your problem. Deoxit may help... but of course replacing the sockets would be better. I just pulled out my machine to check which chip it was, and it was L6. That socket was bad on mine and it was what was creating the blue trails. None of my...

My trails were blue and skinny, the same color as the cursor. Try reseating those chips!

Also try reseating the other socketed chips on the board. Mine drew lines that matched the cursor, and some other odd graphical issues. I checked a lot of the repairs on brzecki's site but none matched my symptoms. Tried the piggyback on the common chips that fail, but saw no change. Braze or...

Okay, I missed that it has d and E on the boot sequence too. Must have looked away at the wrong time. And now that I hooked up the seat I hear it has a boot chime. Hitting abort a few times gets me some funky music that sounds like I should be selecting a car. Forgot my tpg so I'll have to...

I just picked up a RUSH 2049 sit-down. Does anybody know what the alpha LED sequence should be on a normally operating RUSH 2049? Mine goes 1-9 and then A-C and hangs there a bit, then turns into a horizontal line that scrolls (down? I think?). The monitor is not functioning so I can't see...

LOL touche. I was having a tough time writing that because I didn't have my readers on. :laugh:

Go to Walmart and try on their ready made readers by the pharmacy. Really they are eyeglass shaped magnifying glasses. Try em on small print on the meds which are in the next aisle to get a general feel for what "looks good" (ba-dum tsss) buy em take them home and look at your pcbs and take...

I think I've already found the issue, but hoping for confirmation. Sometimes when inserting a coin (ie contacting the coin door with your coin) the game will reset. It had been running daily for 3+ years now in my restaurant without issue. On a hunch I decided to check if maybe the slam had...

Gonna bump this for another bad socket at L6. Symptoms included crosshairs leaving choppy blue trails and the missile trails were jaggy and not straight. The scrolling words at the bottom became a scrolling black rectangle. Eventually it developed striped explosion graphics and striped "MISSILE...

In case anyone finds this needing the solution, it was caused by a bad 6116 RAM. Found others elsewhere online with similar issues, caused by bad RAM. Used probe on the RAMs. Found one RAM (3rd in row) was not behaving like the others, piggybacked a good RAM on it, no difference. Piggybacked...

I've recently acquired a SF2CE running a bootleg board (with some searching it seems to be an MSTREET-6 board). It's having character sprite issues, where it displays incorrect sprites at places. Not entirely unplayable, but definitely annoying. It seems to be fairly consistent in its errors...

Ah wait, there's an update to replace Nibbler hardware with the Galaxian! Now I have to figure out how to do that! Thanks VC!

I forgot I picked one of those up for Jumpbug... I haven't gotten into that project yet. Thanks VC! **edit: I just looked at the cut sheet. It only has Galaxian. :(**
