NEC PC Engine Duo

This is a weird one! First, some context!



Back in January of this year, we were at Evercon, and were intermingled with a huge array of other exhibitors. Some of them had Turbo Grafx 16 video game consoles, and their imported counterparts, NEC PC Engines. I had quite a bit of fun with them, and thought it might be neat to have one in the WCC fleet.







But what even is the PC Engine? Wikipedia article HERE, but I'll paraphrase.



The PC Engine was a joint venture between Japanese tech giants Hudson Soft and Nippon Electric Company (NEC) to create what was the first "4th Generation" video game system. Released in 1987, it beat the Nintendo Super Famicom and SEGA Mega Drive to the market in Japan, and they sold piles of them. Rather than traditional cartridges as we know them, they used "HuCards" which are roughly the size of credit cards, with a single PCB sandwiched inside with the various ROMS to run the game- similar to the cards used by the SEGA Master System, for those more familiar with those.

The PC Engine was also the first to market with a CD Rom add on, albeit as a kinda clunky add-on that makes the SEGA CD look elegant by comparison.



Further, they had an absolutely dizzying array of variations, including the "Core Grafx" (which has a slightly different, cost-reduced CPU), the various "Super" and "Turbo" iterations that feature differing RAM and ROM combinations to play increasingly more demanding games.

After doing some homework on it, I determined that I wanted one with the CD drive built in, the latest variation of the ROM and RAM combinations I could get, and for $100 or less. No easy task, but I figured I'd eventually find a deal- and I did!

This unit is the PI-TG8 model PC Engine Duo model PI-TG8. This one has both the enhanced CD ROM drive to play "all" the games for the system, as well as the standard HuCard games. This is the same console as the TurboDuo, the second model of the TurboGrafx 16, though the pinouts on the card connector are different. The CD games should be unaffected.





I went with this one as it met all my earlier requirements, and as it was from a US seller without any import fees, the price was right. It came with one controller, an AV cable, and two games- though one is a Japanese HuCard, and the other is a Turbo Grafx Turbo Chip, which aren't compatible with each other. The power adapters for these are an odd thing- the Japanese ones can only accept the Japanese 100V power in, and here in America I don't know that we have a barrel jack plug anywhere close to how huge the one on this particular system has. Though having worked on NEC computers, that totally tracks for them. 😆

When I first got it to the shop, @MattPilz suggested grabbing a laptop multi adapter to find a compatible plug, but between a cheap Walmart adapter (with 16 plug types) and an RCA-branded power adapter kit from Menards, I haven't found one that works. So, I suppose the logical step would be to get a more "normal" barrel jack power connector off of something else, and swap it on the board of the PC Engine. I'm sure I can find something to cannibalize the part off of around here- otherwise a trip to Goodwill be in order! 😁

In summary, this was probably a dumb move on my part. The odds of this thing having capacitor issues (or worse) are fairly high, though I like to think any problems it might have are surmountable. But it is an oddball machine from halfway around the world, and I like to bring stuff to shows people might not have experienced before- and I can say with some confidence most will not have played with one of these before!



Hopefully coming to our next show!

I’ve been looking at getting one of those for my collection along with a Pippin, Saturn, and PSX. I’ve haven’t found one at a good price yet, but I guess I better get searching for a good deal. Hopefully it works or get it going again.

Cleverly, NEC has the power jack on it's onw separate PCB connected to the main board by a series of wires, and the whole thin just lifts right out. I presume this was so they could snap this size plug in for the Japanese PC Engine variant, and a different plug for the US-bound TurboDuo variant. Clever? Sinister? You be the judge.



The photo doesn't really do this justice- the center post of this barrel jack is enormous. Thankfully, this appears to be a stock part in terms of how it interfaces with the board, and I ordered a pack of them (the smallest volume one can easily find is 10) and it's on the way from China now.

I'd gone to Goodwill to find some items with potentially compatible jacks to steal and then "frankenstein" onto the PC Engine, but all of the ones I found have different connector arrangements underneath, and I'm not keen on messing with this more than I have to. I can wait two weeks.

After that, it'll be time to test, possibly recap, and then get to using the thing! Fingers crossed everything will be set in time for the next show!

After some finagling with the power adapter and whatnot...



It loads up to the boot screen!



However, the cards don't work (the unit just loads a plain white screen) and the CDs don't seem to spin at all. As it's a game system, I've let the wizards at Gaming Generations have at it so I can focus down all the other projects piling up!
