...Speaking of which, why would someone advertise a board as 100% working if it won't boot up? To me, that's not 100% working, but being new to this, there's probably language and terms about the hobby I need to find out about....
I don't think it's local to this hobby, but applies to all with sales of parts.
For example, you want to BYO car. If you bought an engine that "100% works", you know it doesn't come with the body or wheels (think engine=PCB/body=cabinet/wheels=monitor/car=game). But it also didn't come with the belts, water pump, gear box, transmission, oil, gas, transmission fluid, battery, etc. Even though you need all of these to drive. Still, the
engine really is in 100% working condition. And if all you were doing was replacing the engine, you'd have all the other parts for the car to run.
As you found out, it's a good idea to know what parts the game needs to run before you buy, but $45 total isn't too bad for a 100% working Blitz PCB. (However, not the best deal either

)
As far as terms go in this hobby, you should assume "PCB" means just the main PCB, unless noted otherwise. An "Upgrade Kit" usually includes all needed PCBs, HDs, a marque, maybe a template and other non-standard parts, and might or might not have standard parts such as joysticks and buttons. And than there are "small" parts such as harnesses (wires) that you need in addition to the more obvious PCB, monitor, CP, etc. The "small" parts can be pretty pricy, too; $45 (including shipping) for a harness is also a "not bad" price.
Good luck, and above all, have fun!
