WTF IS THIS CONTROLLER?!?!

[u/Ordinary-Step29]

I got this controller cheap from a local game store. It has six buttons, so it plays fighting games really well. I can't find ANY information on it. Anyone know what this thing is?

I think you should unscrew it and take a look at the circuit board inside. You'll probably find more clues there. There's likely to be something written on it.

I popped it apart to clean it and unfortunately no marking on the board other than some numbers. . .

Could you post a photo of the board and the numbers on it? Even if there isn't any obvious branding, they might still give us a clue.

If there's really no manufacturer name or logo anywhere on the PCB, my guess would be that it was probably made by a Taiwanese third-party manufacturer or something along those lines.

Happy to!  Please see link below.  Some of the photos may be duplicative, but I wanted to be thorough.

Thanks for sharing the internal photos! I was curious about this controller, so I did some research to see if I could find out who actually manufactured it.

Unfortunately, I haven't managed to identify the manufacturer yet, but I did find some interesting information that might help!

First, I found a few references to the Fighting Sword online:

• The Gamesmen (Australia): https://www.gamesmen.com.au/3do-fighting-sword-controller-pre-owned-complete Probably the most interesting find. They have a complete boxed example, with photos of the original packaging, including the back showing all its features. They also list an estimated release date of 1995.
• VGCollect: https://www.vgcollect.com/item/264397 The controller is listed in their database, although there's no confirmed manufacturer or release date.
• Jungsi's Corner: https://www.jungsi.de/en/panasonic-fz-10-3do/ Another documented example in a 3DO collection.
• eBay: https://www.ebay.com/itm/257759497256 Another example of the same controller.

Now, about your PCB photos:

I examined the markings on the circuit board and found a few interesting clues.

1. Integrated circuits

There are three main chips:

• CD74HC14E
• CD74HC166E
• CD74HC166E

These are standard logic chips rather than custom-made controller ICs. They appear to have been manufactured by Harris Semiconductor, but that doesn't tell us who actually made the controller.

2. Manufacturing date codes

Two of the chips have the following markings:

• H 9444
• H 9448

These most likely use the YYWW date format, meaning weeks 44 and 48 of 1994, respectively.

If that's correct, and assuming the components are original, the controller couldn't have been assembled before late November 1994.

This would fit nicely with The Gamesmen's estimated 1995 release date.

3. PCB identification markings

This is probably the most promising part if we want to identify the actual manufacturer.

I found these markings on the circuit board:

• TPC-03D2
• YK-94-2
• YK

Interestingly, YK appears in more than one location.

TPC-03D2 looks like an internal PCB reference, while YK-94-2 could be a manufacturer code, project identifier or board revision. The 94 might also refer to 1994, although that's just speculation.

I couldn't find any confirmed matches for these references, unfortunately.

4. The original packaging

I also examined the box photos from The Gamesmen.

Surprisingly, none of the visible sides identify a manufacturer, distributor or country of origin. There's no visible barcode or product reference either.

The packaging simply uses the Fighting Sword name and describes the controller's features in somewhat awkward English.

The Gamesmen lists Panasonic as the manufacturer, but I suspect that's just how their database categorizes 3DO accessories, rather than a confirmed attribution.

So, what can we conclude?

The controller appears to be a genuine mid-1990s third-party accessory, probably manufactured around 1995.

My initial suspicion was that it might have been produced by a Taiwanese or another Asian OEM manufacturer, as was common with third-party gaming accessories at the time. However, there's no actual evidence confirming its origin.

The most promising leads are the PCB markings YK, YK-94-2 and TPC-03D2. If someone ever finds another controller or accessory with similar markings, it might help us trace the original manufacturer.

So unfortunately, I still can't tell you exactly who made it, but at least we've narrowed down its likely manufacturing period and found some references that could help with further research.

I hope this helps! I enjoyed digging into this little mystery. :)

Thanks for the insight!  Such an odd piece of gaming history.  Maybe it will never be identified, but I think we got closer than anyone ever has
