Question

Hi folks,
Ive just purchased a Guitar Freaks 11th mix machine and am hoping to resurrect it.
The information I have from the previous owner is that it was in complete working order, the CDROM was removed to be tested in another machine and didn't get put back. It got mixed up with other drives and thats where it sat for the last 4 years.
So I have purchased the machine along with 6 CDROM drives, that hopefully one of which is the correct one. I know this hardware is fussy with optical drives, so it may be a challenge to find one that will work. Between myself and my work I can probably come up with another 10-15 drives to try.
As this is my first Arcade repair, Im posting here for some advice. I did repair a couple of pinball machines last year and had good success, with some fantastic advice from these forums.
The machine is a Japanese import and apparently has been converted to 240v. Ive had a look and it seems the original transformer has been replaced with a 240v in the unit and also in the external speakers.
This thing seems to consist of 3 main units. The power supply, the computer and some other box that I think is audio amplification.
The Computer is out and apart to access the CDROM, with the exception of the audio RCAs this seems easy to plug back in.
The Audio is strange. There a 3 pairs of RCAs on the computer, audio out 1, audio out 2 and a black pair with no label that may not be Audio. Im assuming the RCA cable goes to Audio out 1.
The RCAs go from the computer to the external speakers, one of which is full of amplifiers. Then it comes back and plugs into the 3rd box that I think is also amps. The cabinet speakers lead to a plug that goes to the external speakers, so I assume the cabinet speaker amps are in the external speakers.
The 3rd box also has two plugs that have orange and black wires leading to the power supply that are not connected. I dont know if they ever were. So Im assuming it has no power and doesnt do anything
I am wondering if this is because there are external speakers and perhaps the whole thing can be reconfigured just to use the cabinet speakers. This would be handy for me as the external speakers make an already large cabinet extra large and Im unlikely to need the extra power.
I have not powered the unit up yet, as I wanted to ask if there is anything I should check before I do.
So here are my questions to get started.
1- what should I check before I power it up ?
2- Does the computer receive its power via the Jamma port, because I cant see any other power to it.
3- Does anyone here know about the audio system on these things ?
4- Any Advice on which CDROM drive this thing needs ?
Sorry for the long post and potentially stupid questions, Im always keen to learn so all advice is welcome :)
PS, anyone in Adelaide who wants to pop around for some beers and help put this old dinosaur back together is most welcome ;)
