I like to take things apart and put them back together again. Always have. My parents would come home from running a few errands and would find any number of electronics items from throughout the house disassembled on the dining room table. VCR, Computer, Stereo, anything I could get my hands on. Oddly enough, I never took apart a video game system when I was young. I was so afraid that it wouldn't work after I put everything back together and I didn't want to deal with the emotional turmoil of not being able to play RBI Baseball or Blades of Steel. Flash forward a few years and I have no issues taking a game console apart. So imagine my surprise when I do a little searching online for a Sega 32X teardown so I know what I'm getting into and I can't find one. I'm sure there a few out there, but if I search for something on the internet and what I'm looking for isn't in the top 4 or 5 returned pages, it might as well not exist.
Here we go, I'm sacrificing this 32X just to get a closer look at all of the little bits.
Just 4 screws separate you from the inside of this little beauty. Grab a philips and go to town.

After the 4 screws on the bottom are gone, there are 10 philips screws holding the RF (Generation) shield down. Once we remove those, we are in for a surprise...

Huh. That's a bit of a surprise...Not really much goin on here. We can see the cartridge slot right on top and a bunch of capacitors, resistors, a few ICs but not much else. We have to dig deeper. We must find where the power of this machine is stored.
While we are here, let's point out one of the common points of failure on a 32X: The ribbon cables connecting the upper cart slot to the lower part of the system.

2 ribbon cables connect the cart slot on the top of the system to the guts on the bottom. The cables can appear to be fully inserted but the system doesn't work. It actually takes a good bit of force to remove these cables so be very careful. Once they are removed, reconnect them making sure they are even and inserted as far as they can go. Feel free to test the system before you put the top back on.
Let's move on.
There are just a couple philips screws holding the upper board down. Once they are removed, you will find a few wires preventing you from lifting the board out. Cut them. That's right, I said cut them. Pretend you are diffusing a bomb. It will also give you a chance to practice your wire soldering skills if you ever want it to work again.

We have lift off
Wait a minute...There seems to be something else lingering down there...

A couple of philips screws later and we have freed the Genesis cart that never was!

Gotta get inside there. Have to see where this ultimate power originates. Just a few. more. screws.
Eureka! The source of unlimited power!

That Sega IC on the right is just an 8 bit 20mhz digital to analog converter, the one in the middle is a custom Sega IC (I don't know what it does) but that IC on the right...what is th..could it be?

IT IS!!! It's a Super H! Or, a 32-bit Reduced Instruction Instruction Set Computing processor. WE FOUND THE RISC! This chip would later be used in the Sega Saturn. So I guess you could say that the 32X is the father of the Saturn. I know you won't, but you could say that.
There are a couple other ICs on the board from the regular players like NEC and Toshiba but the Super H is the star of the 32X. I think it's really interesting that the majority of the power of this system:

Is right here:

Thanks for coming on this little teardown journey with me.
Nice one, Bil. I also tear things apart, and it's interesting to see what makes these things tick.

so hot

No, literally. The 32X ran hot, that's why they came with clips to keep the dust flaps open. Of course, why did they have them in the first place if they're going to stay pried open anyways?

I was always paranoid about this sort of thing when I was a kid as well. Didn't have the same feelings about my Tiger games, which is a shame.
So that is a naked 32X, huh? It's so... tiny. Much smaller than I ever expected it to be, considering the size of the unit. I even went and read up a bit regarding these Hitachi chips. There were several generations of these chips, with some of them ending up in Sega hardware. The Dreamcast for example, used the SH-4 chip, which was developed exclusively for it (at the time). The Saturn uses both the SH-1 and the SH-2 chip, so one could say that the Saturn is two 32X machines taped together ;P

@bombatomba: So that is a naked 32X, huh? It's so... tiny. Much smaller than I ever expected it to be, considering the size of the unit.
That's what she said....... Sorry, too easy. Nice article Bil! What makes it tick hardware articles are always interesting.

I guess that kind of explains the existance of the Hitachi Hi-Saturn...
|
Nice post bill, undressing that 32x, very RISCé.
|
Thank you for this. Information is to me what food is for the rest of humanity, and you have given me some fuel to continue forward in life with.
|
I'm pretty sure it's not necessary to cut the wires...
|
@mumboking: It is if you are CSI.
|
I will be adding a 240p Component output to a 32x soon just to see if i can !
