A while back I posted some pictures of my Korean SNES (Hyundai Super Comboy, 현대 슈퍼컴보이). I finally took my Korean NES (Hyundai Comboy, 현대 컴보이) out of storage and took it apart to clean it and take some pictures of the motherboard. The Hyundai Comboy has the front loading "toaster" form factor, just like the U.S. and European models. The motherboard has "1992 Hyundai" printed on it, and it is a model NES-CPU-10K. (I assume "K" for Korean region) A couple observations/ thoughts: - The Korean NES here has an RF out port. I am not sure if it actually works on a Korean television set. (the Korean SNES version I have lacks an RF port, and another poster here, TriMesh, said this is due to the VHF TV band in Korea having a gap between 88 and 174MHz) I wonder if the RF modulator for this motherboard was manufactured specifically for the supported Korean VHF TV band frequencies? - Please correct me if I am wrong about this, but I think the region lockout for the Hyundai Comboy is region specific to allow ONLY Korean-region NES carts. In contrast, the Hyundai Super Comboy will play Korean, USA, and Japanese cartridges. - Again, just like the Hyundai Super Comboy, we see Hyundai brand RAM chips here (part no.: HY6116CLP-10 9245A KOREA). I wonder if Hyundai insisted on using their brand RAM chips in all Hyundai Nintendo consoles?
Cool stuff. Could you take some pictures of the exterior of the system? I would assume the logos would be different, if nothing else.
@らりるれろ Here are some pictures of the case and some of the stickers unique to the Korean Hyundai version found on the case:
Also I found these pictures online (of Hyundai Comboy games) from a user called comboycrazy from NintendoAge. These pictures of Hyundai Comboy games ARE NOT MINE: http://imgur.com/a/1ST51#0 I am definitely jealous of that impressive collection!!
Just a note here on the RF presence, and a reference to your last post about the Super Comboy. The RF-less Super Comboys were the last made and are not nearly as common. Of the 6 or 7 revisions to the board that were made, all but the last and possibly last 2 had RF. It took me several months to find one like yours. I even had a 1 Chip from 1996 that still had RF. I think you got lucky! Your regular Comboy here is especially cool because it was produced while Hyundai was simultaneously making both Comboy AND Super Comboy.
Also, one more edit. I recently sold a Comboy like yours so I got to test it on my Korean TV before I sold it. I was able to plug it in with just RCA and Audio outputs from the side of the machine. It worked great. The RF was identical to the US one as far as I could tell. Probably the strangest thing is the AC adaptor which takes in AND outputs AC to the unit. But the input is identical to the Famicom and Super Famicom. You can actually plug in 9V DC into your NES and it will work fine. But NEVER plug in a US or Korean NES/Comboy plug into your Famicom/Super Famicom or you will break something.
Same applies to PAL SNES PSU is just a transformer and console has diode bridge so console will eat anything in 9-12v range AC or DC, but using PAL PSU with SFC or US SNES will kill your console unless you modify it (add diode bridge and 1000uF cap).
It looks pretty cool. I like the Comboy logo. Interesting how it says both Comboy and Nintendo Entertainment System. It looks like it's a little yellowed though, that's a bummer.
Yeah... unavoidable oxidation of flame retardant plastics... I'll just call it a "patina" and try to feel better about it haha.
