Voltage Reg. Currently not available to order. Out of Stock. Ni-Wumpf Gottlieb System 80 driver board. Using a transistor array is neat, but costly when one lamp in the array fails! Generally, boards are worked first in, first out. There are a few exceptions. NOTE: My queue at this time is about 60 days deep. This is a good thing! I just swapped in my other gottlieb 80 board from Time Line and Circus boots no problem. I noticed the Time Line cpu still has the origional Data Sentry battery and its going to stay right where it is.
Perhaps I should have chosen a different system for my first solid state project job. It looks like these Gottlieb system 80's are monsters to deal with. I do have other bally and Williams solid state projects like Embryon,Police Force and Scorpion that I should probably move to. Your right John. I am motivated not only to fix this Circus,but to learn due to the fact I have so many machines. Last night I went through the manual and think I may have discovered the list of which legs on which chips are the address lines.
I wrote it all down like a graph. So I did that for all 15 addresses. I found that addresses A0-A6 went through every chip. Then addresses A9,A10,A11 only went asfar as U3. And addresses AA15 did not go anywhere from U1. Maybe every game is different and that is why there is no ''set in stone'' graph anywhere on the internet? So now I think im supposed to use a logic probe and follow each address path through the various chips?
Hi John, Thanks for the breakdown on whats needed to know for each system. I think im getting somewhere with this. I understand what Ed asked me to check.
Every one of those addresses showed high with the logic probe. So I tested those legs and I found one dead leg that didnt register a high or low. Ed also suggested checking the outputs of chips Z10 and Z12 and here are my findings.
Those are both 14 leg chips,so im assuming legs are the output legs. Z10 Leg 9 was low. All others were high and 2 were showing both high and low. Z12 8 high,9 was dead,10 low,11 dead,12 low,13 high and 14 high.
Does this indicate a problem? The effect or removing the battery or adding the ground was likely not the cause of the problem.
Yet your actions could have damaged a static-sensitive component, which can happen by simply handling the board. Were you protected? Is your soldering equipment protected? I have some factory System1 bags for board transport that state ESD warnings all over them.
Just removing and replacing a board form the backbox can make it go from working to non-working, if you're not careful. Hi Kah, I had no idea about that static thing could damage a board.
That is very helpful information that you posted. No I was not protected nor was my soldering iron so that could very well be the reason the board will no longer boot.
I always suspected something about using that glue gun may have caused this. I feel I have really advanced,I was able to find the 12 address lines on all the chips by myself and able to take readings from every address. Then I found the AB addresses by myself and was able to take those readings as well. Unlike the 12 address lines from all the chips that were all high ,the AB lines varied and some were even dead. So I have all the test results and now have to search what these results mean.
I do feel as though im not far away. Frank Furhter. Gott Lieb? Hi Ed and Jim. I just rechecked the clock and it is fine. U1 pins 37 and Z3 pins 10,11,12,13,and U4,U5,U6 pins 39 all pulse high. I just redid the continuity check of the Z2 and Z3 pins and all is fine. All the address and data lines are fine. Some other things I noticed are that both Z11 and Z12's inputs are low and outputs are high.
Z13 and Z14 inputs are all high and only 1 of their 4 output lines were high and the other 3 were low. U1 pins 35 and 36 are dead. Z10 pins are 8 pulse high,9high and low,10 pulse high and low,11 pulse high,12 pulse high and low,13 pulse high,14 high and Z12 is 8 low,9 dead,10 low,11 dead,12 low,13 high 14 high.
