Title: Zoo Keeper hates me all day Post by: DrEric on October 20, 2016, 10:18:02 am Hey folks,
Been working on this Zoo Keeper and here is what I know. All ribbon cables swapped Reflowed .156 pins 4116 all swapped New PS Rebuilt the monitor And I still get all video board lights blinking constantly. After a few minutes, this shows up on screen. Could use some direction!

I had a lot of trouble getting my game to boot initially. also, did you install the coin bypass rom? Turn on game with coin door open then play with reset on PCB. Battery on PCB?

New coin door eprom installed and recharge battery installed off the board. I think my reset switch is stuck or corroded, so it doesn't push in any more. I'm going to drowned it in contact cleaner or get a new one. Any recommendations on replacements is greatly appreciated.

So...I turned it off and on, just to check. All LEDs on solid. I do get a rolling screen; looks like this...
Any thoughts?

These boards suck. IT's just a lot of fiddling. Remember too... you could have bad RAM sockets also. Are you getting +5 and -5 to the 4116s? Title: Re: Zoo Keeper hates me all day Post by: DrEric on October 31, 2016, 12:24:26 pm I put in new ribbon cables and reflowed the connectors on the board. I will start measuring chips at this point. Ugh

The pros: I kept all of the original components as is. Cons: I got to a point where I wasn't enjoying the process of constant non working troubleshooting; so I made a choice. I feel defeated, but at this point, I am ok with what I do have. Choice: sell or enhance? Enhance! I installed a TAITO JROK and adapter from arcade shop to help keep all things orig. easy to install (and uninstall), this (http://uploads.tapatalk-cdn.com/20161117/fc78ab045aad1631c2ba469a6eaf3921.jpg)(http://uploads.tapatalk-cdn.com/20161117/298a7955ca28d56fe3595eae6041c810.jpg)creating a functional game. Call it defeat or agility...I am happy that it plays what I wanted it to play. Sent from my iPhone using Tapatalk |
