These are important to me:

Detailed game manual that includes menu & adjustments of the software, illustrated parts drawings, and electrical schematics. Take a lesson from Chicago Gaming: they include just such a manual with every machine they sell. It's just like the original Williams manuals were and around 150 pages in length.

Playfield prop stick. If Homepin can include it in their machines, so should you. I'm not gonna climb on a fucking ladder just to work on the flippers. I'm getting sick of sawing off a pool cue stick to make my own prop sticks.

Service outlet. I need one to plug in my soldering iron.

Wire the bill acceptor socket for both 12 volt DC and 120 volt AC bill acceptors. Lots of operators still use 120 volt ac bill acceptors. Having it wired for both voltages would allow a person to use either voltage of the bill acceptors they already have.

Include a list of factory approved "options" a machine owner can buy and install himself such as knocker kits, shaker motor kits, fancy lighting kits, etc.

It should be in 8.5" x 11" format NOT 11" x 17" like ACNC is. Costs too much to print out at Fedex Office because I don't have a printer that does 11" x 17" paper. The only thing that should ever be 11" x 17" format is schematic wiring diagrams. Look at how the Williams 1990s manuals are put together. Now *those* are manuals the way they should be! They give the "on location" service tech everything he needs to know including part numbers if something needs to be replaced.

Mount the amplifier unit on a bracket that holds it at a 45 degree angle so that it can easily be seen and adjusted from just having the coin door open. That way there is no need to remove the playfield glass and raise the playfield. A person could just open the coin door and reach in to change the settings on the amplifier.

That's why I suggested mounting the amplifier on a bracket which holds the amplifier at a 45 degree angle near the cashbox. That way an owner can simply open the coin door and turn the amplifier controls easily. It would be very easy for the factory to stamp out such brackets.
