This is a 2011 DOS Aldine Gamebox (AKA Redbox) 400-in-1 Jamma multi-arcade. I upgraded the HDD to a $20 IDE SSD (DOM). Getting there wasn't simple, so I've documented the process below. I also upgraded its fans, ram, and processor along the way.
Original RAM: 2x128mb PC133
Maxed out RAM: 2x256mb PC133
Original CPU: 900MHz Celeron
Replacement CPU: AMD Athlon XP 2600+ 2.6GHz AXDA2600DKV4D. The fastest/newest CPU for the motherboard's architecture, but any Socket 462/370 works.
CPU Fan: 60mm x 10mm to 15mm (must be low-profile)
Case Fan: 60mm x 15mm - 2-pin red/black
CPU Heat-sink: The original is well made, so I applied arctic silver and reused it. Any replacement would have to be very short.
Original HDD: 6.4GB Quantum Fireball EX
Replacement SSD: Any 8GB or higher IDE SSD DOM module. A cheap SSD DOM uses little power, runs cool, and it will probably never die. My DOM measured about 4mbps faster reading/writing.
Replacing the Hard Drive
The Gamebox is locked down so it won't boot unless the hard drive is an exact byte-for-byte raw clone of the original (with exact partition sizes, etc). In other words, the Gamebox is permanently unusable if the hard drive dies. However, once you have a working clone HDD image, it's as simple as restoring the image to the new DOM.
It isn't easy to make a bootable clone though. I did find a program that works after trying all of the common apps. You must use HDDGURU.com's HDD Raw Copy Tool. The reason why DriveImage XML and all others fail is because the Gamebox has a sector toward the end of the drive that results in copy failures. It could be that my drive was going bad, but the drive only shows 4K in bad sectors and I imagine this is actually some kind of copy protection.
You'll need a 40-pin IDE male-to-male adapter in order to attach the DOM to a computer to set it up (unless your computer has IDE slots of course). If you don't have an IDE slot on your motherboard, you'll need an IDE-to-USB or IDE-to-SATA converter to connect the drives for cloning.
