Quoted from Quench:

They're called wire-wrap sockets - an oldskool way to prototype circuits:

Quoted from bicyclenut:

That must have taken them longer to wire up that Jones plug, then to just wait for the right connector to come in.

Quoted from Jahkub:

Also, look at that beefy spring. Haha

Quoted from MrBally:

We had ten EBD's in Detroit-area Billiard rooms including a"chain" with four locations. One of them did $450.00 to 500.00 per week. The others at least $250.00
All on a 50-50 split.
Lost World was pretty good at $200.00/week. Kiss started out good at $250 but quickly tanked to $125 to 150. We got our first allocation of five from Empire Distributing (who became Bally Midwest). Before we got our 2nd five, we saw the coin drop tank so we cancelled the rest of the order. We let competing operators hold that bag.
Examples of throwing stuff out were Williams Hyperballs. Into the dumpster they went. We had to smash them with sledge hammers first. They went from bringing in $400/week to under $40 in under two months. Distributors would not sell them on credit. That was the big warning. I kept one backglass and set of boards. I eventually threw out the boards as they were useless.
The best example though were the Mylstar M*A*C*H 3 laser disc games. We had ten of those expensive hunks of junk (one was the sit-down model). They started out bringing on $600-700 per week. A few weeks into it, they started failing. Laser disc player repairs were slow. Operators stopped making payments on them. Distributors demanded payment or they would repossess them. We said great; no need to repossess, we'll bring them back to you. You already have the broken Pioneer laser disc players so you can have the rest of the hardware.
They said wait, just give us the Rom board and keep or shitcan the rest. They even gave us the repaired laser disc players back as Pioneer repaired them. Every service tech had a laser disc player at home. We threw the cabinets into the dumpster, one per week. All we saved were the coin doors and cashboxes. This is basically what killed Mylstar.

Bally - Party Zone
Captain Bzarr solid head. Made with some putty, no jaw movement, just side to side.

Very true. This was an hour of my life, but that included dying the new DE targets. [quoted image]
