I am tearing down a NAND Type-3 Triforce arcade unit. It's a little bit banged up, but supposedly it works. I am a hardware n00b, but I will try not to 8-bit-guy myself and blow it up. (Sorry, David.) The screw threading for almost every screw is messed up, so it seems inevitable that screws in here will be stripped eventually. Another Triforce unit I touched didn't have this problem, so I guess this one has had a rough life.
I'm not sure this device is actually strictly a network card, but it has a receptacle for an RJ45, so, close enough.
Security Key Breakout Board
The Triforce has a security key system like its siblings NAOMI and Chihiro. My understanding is that these security PIC chips just store a small DES key, and that key is used with DES in ECB mode to decrypt data out of the flash. This breakout board attaches to the media board. It has a few components of its own, but not much.
Finally getting into the meat of it.
Back in the case
With all of these components removed, here's what's left:
The "Main Board"
It's a DOL-001. This is not a shock since this has already been known for 10+ years. Still, it's kind of funny to see it.
I did not take off the heatsink. I don't have spare thermal pads in the event that any of them rip. Still, I anticipate that it looks the same as a DOL-001 underneath.
Power Breakout Board
Once again, I am sure this is not just a board for power delivery, but I'm calling it this since it has the power connectors on it. It's also got some DIP switches and other stuff going on. One of the conectors is labeled "RS232" and another labeled "MIDI", sounds like fun.
Like all good teardowns, I was rewarded with an extra screw after everything was put back together, the sign of a job well done :)
