Since we all love Robert stories (and I hope to be able to share a bunch more of those soon), it's easy to think of deeproot as nothing but a shit show.
However, there were also smart people at deeproot who dedicated a lot of time and effort into projects that will unfortunately never see the light of day. I'm glad to be able to share some of their work so it doesn't totally disappear down the memory hole.

Technology/manufacturing nerds, I'm counting on you to bring color to whatever the hell we're looking at.

LED current @ 5V... I think =P

I/O board. Daughter boards had access to 12v & 48V. You would essentially build a custom machine by populating the coils or lamps/motors daughter boards. (https://imgur.com/9izeOEJ)

Then we made 12V or 48V only boards. Same thing as earlier but the Inputs were removed.

Voltage isolation is a necessary evil.

LED indicators were really nice for troubleshooting

Surely no one would install these backwards ...

The green boards were expensive, so we added most of the components to the main board and only made the mosfets removable. (Small green board) I think some people love thru hole components because they like inserting things in holes....

RED 5V, BLUE DIG, YEL 12V, VIO 48V, but we ran out of VIO so we used red, T H I C C instead...

Able to kill the 48V for servicing mechs inside.

These were neat boards. We ended up not need to replace that many mosfets at this stage. However, we figured it would make demo to show a quick repair.

We measured other games flipper strength, like dialed in & gophers. (https://imgur.com/f1rJLfA)

So this is fun. The brown noses would ask for 10 games worth of boards. We would optimize our sheets to lower the cost. 2 weeks later they would arrive. Then we would only receive parts for 2-3 games. When asked where the remainder of the parts are, they would reply they ordered less because money is tight.

Cable tested, we couldn't afford the rights parts sooo better than nothing.

Someone forgot to order the fuse holder. The substitute works.

This was for the cycle tester! Someone forgot to cal the voltage regulators and signed off as "CALIBRATED"
