OK, I got home and waited... waited... waited... and my friend was a no show. Go figure. So I embarrassed myself and asked my neighbor to help me offload the cab from the truck into the shed. First thing he asks is, "what do you want this for?"

At least he had a dolly and just happened to be some kind of mover for a living. How convenient. I'm sure they think I'm sort of nerd... oh wait. He warned me that in exchange for helping to move the cab he wants me to clean my front yard.

Anyhow, got the cab off and into the shed. First things first, I decided to take stock of the condition of the cab.
Contrary to my initial memory of last night, it is indeed a 100% Hang-On cab, not a conversion or anything of the sort. The Marquee appears to be in excellent shape except for some sticker residue. The tax sticker?
The steering bars are not so great. I removed the plastic cover last night (which I almost lost during transport). It appears both the throttle and brake controls are missing. There appears to be some damage to the harness as well. Movement feels right, but I don't know if it works without wiring it up for a test.
The monitor looks like it was flat out removed. Whoever did it just cut through the wires and left them dangling. I'm guessing the previous owner used it for another Arcade cab, but that's neither here or there.
The trim needs some minor work. Most damage seems to be out of sight, such as around the left side where it has some strange rippling. The side art looks very good. It's not a sticker, but painted on, so it might be possible to touch it up with some color matched paint rather than strip it bare.
Except for the locks, the coinbox looks 100% complete. The buttons say ".25 x2" so I assume this was originally set for $.50 play. There are pairs of 1/2"(?) bolt holes above and below the coin box, I assume from lock bars of some kind. Putty and paint should fix that right up. To my surprise, a set of keys were hanging from a coiled spring. Turns out these belong to the lock around the back! Even better, while I was looking into the space for the coin mech, I saw shadows of what appeared to be a bunch of IC's. I was told the cab was lacking a PCB, so I figured this was some stray PCB for the coinbox or something, but I was hoping.
I was happy as soon as the key turned in the lock, it would save me the hassle of drilling the lock out. The less destruction I do to finish the job, the happier I am. As soon as I opened the back door, I knew I struck gold. The entire PCB appears to be mounted and intact along with the power supply and some other misc components. SWEET!

Another surprise is that I found an instruction card for some version of columns, a sheet of conversion side art(?) Road Riot 4WD, the smoked plastic monitor cover (damaged), and two shadow masks one with an official SEGA product sticker. Some misc metal parts and an unidentifiable PCB board.

The mounting posts were damaged so I assumed they fell off of the PCB stack, but I couldn't find an obvious mounting place. There's no real identification other than what appears to be serial numbers and the SEGA logo. Maybe it's the monitor PCB?
About this time, my friend decided to show up. He was all over the cab like white on rice. He's really pressuring me to rip everything out and convert it to MAME. He did, however, confirm some of my suspicions, but couldn't (or wouldn't) tell me anything about the PCB's other than it's a Jamma (KLOV says otherwise).
All in all, it looks to be a very salvageable cab. I can rebuild it as a Hang-On cab and use it to help pay for a different cab or completely gut the cab for MAME. Unlike my friend, I'm a big fan of original hardware. Even though I generally play classics on my PC, I still like the feeling and quirkiness of firing up old hardware and playing it just for

and giggles.
I checked out KLOV, but they don't seem to have the schematic for the wiring harness or PCB. Major suckage. It's too early to tell what wire does what, so I can't say how much damage the harness has. Worse yet, I have a limited idea what kind of monitor it will accept, much less what cut wire does what. Most of the wiring throughout the cab appears intact, it's just the ones that I think lead directly to the monitor that've been cut.
I haven't inventoried anything else yet.
