I have just bought a 1979 Genie on eBay in the UK, my first Gottlieb.
Gottlieb System 1 games are rare over here, so very few UK guys know anything about them.
The games is complete, boards and connectors seem tidy with no ugly repairs, but it is non-working. It makes sounds when you power it up, it blows a GI fuse, all the displays are all blank.
The System 1 boards seem to have a very bad reputation. Do System 1 owners try to keep the original boards alive - replacing old capacitors, earthing them properly, replacing connectors etc ..... or do you just replace with modern boardsets please ?
