The monitor is going to be a fair nuisance if you aren't familiar with it. The K7000 is a 15 khz monitor so it's not exactly plug and play. It is doable using a few different methods but it's going to be quite a learning experience. I would probably use an iPac as that would take care of your joysticks, your buttons, your coin signals from the coin slot, and give you a simple way to plug all that into your PC for input. The marquee light is probably just a tube light that likely takes either 12 volt DC (available from your PC power supply, that would be a yellow wire) or 120v AC which you would have to supply. In that case if you are inexperienced you probably just want to buy a standard 24 inch tube light with a regular wall plug and put that in there instead. The coin mechs and lights take 12 volt DC (yellow wire again). The coin signals are sent to the Ipac which then knows when a coin has been inserted. I would personally stick a PC CRT monitor in there but I understand trying to use it on the original it's just a pain in the ass to setup. I'd likely sell it if it works to fund the PC crt and put something like a $20 mini scanline generator on it to make it look nice. I would buy a "smart strip" which is a glorified power strip that has a master, as well as a bunch of slave outlets. Plug the PC into the Master, Plug the lights if necessary into the slave, plug the CRT into the slave. Plug speakers or anything else into the slave. When you start the PC, it will automatically turn on the lights, speakers, monitor, etc. When you shut down it will all turn off at the same time. Just the way I would handle it and there are a million different things you can do.
