All of the programing/sounds/music eproms are all new with the newest coding of said eproms.
And yes for those that are wondering I saved the old eproms and are placed on anti-static foam and then inside a anti-static bag.
That I have then put into my Police Force cab. :)

Woah...

For a moment I thought I was looking at a MAME machine with all those daughter boards, until I saw the Solenoids and massive amounts of I/O and its dedicated expansion board.

Did you have an Eprom reader to try and extract a backup of what you have?
Are these burned firmware Eproms used in the machine?
How did the PSU recapping go? I see shiny very modern looking Electrolytic caps there.

This is so neat. :D
There was a real beauty in these machines. I'm not too familiar with them but I am familiar with old electronics and the nightmare that comes with doing repair, especially when Corrosion is a concern.

That moment I notice the OPM IC. So you had FM based music and PCM's from the Eproms. :o

The longer I'm looking at this... AHHH! Is that a 68xx?

I do have a eprom burner but I bought all the eproms new from a pinball website.
I wanted to keep the original Prototype eproms so I bought the up to date eproms.
And yeah everything in the pinball machine is like a computer.
There is the main big board that is like a Motherboard in a computer then you have the Flipper board and a Sound board and a display board too.
And of course the power supply that has different voltages that will then go to the other boards
And there is a board called the interconnect board where all that stuff plugs into that board then the playfield plugs into that board.

I do a lot of electronics repair. So its exciting for me to come across something that uses multiple processors and peripheral comms to interface with a machine and its physical parts. :D

I should upload my pinball boards that I bought in a kit.
It is for my own pinball machine I am working on.

It is similar to the Police Force boards but is much smaller. ^=^

Well, I'm watching so I'll catch it if you upload or share it in a DM. :3

Very interesting. Just to think of all the architecture, and the program, and electronic connections, and mechanics...

The neat thing is that the Fast Pinball boards I am using for my own pinball machine pretty much uses the same boards but just much more smaller in scale. :)

Hm. The whole controller board can be replaced by a tiny modern chip. But I guess the power control part hardly can become smaller?

I can take pics of the Fast Pinball boards.
The power filter board is smaller too.
It has 3 massive electrolitic caps on it and some mini-fuses to it.
