First Look: Gottlieb Target Pool and adjusting stepper units

I’ve been on the lookout for more 60s-era Gottliebs with the small flippers. We don’t have hardly any in the collection and after hearing Bowen Kerins say “Target Pool” was his favorite game from the 60s, I knew I’d made the right choice in picking this machine up. Unfortunately, I never turned it on or checked it out electrically/operationally before I bought it. But I could see the game was complete and the seller said it did work. This was one of those times where I knew I was going to get it any way. So here’s the first look so far, a playlist of 3 video clips covering the initial examination of the game, and finding out what’s wrong and fixing some issues. This is a good example of how to fix certain problems with stepper units.

If you watched the previous story on the Target Pool you may see the same first-two videos. I am keeping them all together in case someone sees this story by itself. If you’ve watched some of the videos in the series before, just hit next on the player to skip to the next video.

Changing Ball Settings On Gottlieb EM Pinball Games

I’m slowly catching up on the maintenance of various games and working my way down the EM row. One thing I wanted to do was switch one of the games from 5-ball to 3-ball. I feel some of these games are a little long on 5-ball and since they’re on free-play and there’s dozens of other games around, a shorter game time is recommended. In the video below I go over how to make changes to game settings on EMs like this…

Adding a memory capacitor to a Gottlieb Sys80 “Jacks To Open”

Now that I’ve got space to pull more of my project machines out to work on them, I’m diving into Sys80 stuff. The first order of business is to work on a “Jacks To Open” machine, which is a solid-state remake of Gottlieb’s popular wedgehead, “Jacks Open”. This game came with the battery removed (or maybe I removed it when I got it – I don’t remember honestly) but the MPU board was in good shape, but the game wouldn’t remember any settings because obviously, there was no battery-back-up.

This is a simple fix, and for these games it makes more sense to add a memory capacitor than a remote battery pack, so in this 4-part series, I go over adding the memory capacitor to the machine. Check it out:

Re-pinning System 80 edge connectors – Gottlieb Mars God of War

I finally found some time to take a look at the Mars God of War I pulled out of a hurricane katrina-damaged house in New Orleans last year. The batteries on the MPU board had hosed the connectors as well as the main board and I am set to replace it with Pascal Janin’s PI80x4 board. In preparation for that, I have to re-pin some of the damaged connectors… as this video shows, things are never as easy as they seem…..
