[Console Repair/Mod Center / Re: RGB to Component (YUV) converter options for TurboDuo / PC Engine]

There are two variants on this circuit I found (though the circuit build is self explanatory, given how the IC does everything for you.)

There's an AD725 chip (this one off a Neo Geo RGB mod page):



And an AD724 (this is off a SCART>svideo mod page):

Now it looks like these are basiclly the same chip, I bought a 725. They are not cheap sadly (£11) but they go down to £6 if you buy 100, I don't have £600 to throw away on a chance though.

I need to buy more caps but I have the IC and the NTSC crystal which form the core of the mod, and I guess you integrate said mod with a PCE amp.

I will review the circuit when I can put it together. Has to be better than native composite. I have a TV which takes raw NTSC through composite so I'm sure it'll accept s-video too, the IC does do PAL but PAL users have SCART so I'll review how to perforns through NTSC.

[Buy/Sell/Trade / Lots of PCE in Florida]

OK all this is at my fiance's house:



And it is going on eBay, as we want to bolster an account up with feedback to sell PCE from Florida. But if there is anything anyone wants in that picture please mail me with an offer and hopefully I can set up a sale on eBay for it, I am looking for nice feedback for our new US selling account.

Now most things in the pic are in B condition apart from stuff that's missing the case etc, and I think Dracula X had the spinecard too. Of course, we can check over the stuff and I have instructed my fiance how to judge condition.

These are things I bought from Japanese sellers and made them post to the USA not the UK because I do not like paying 50-80% in customs and import tax tariffs, nope not at all. Just in case people were wondering.

m the + end of the 10uF capacitor on the HuCARD port board (this part should mean nothing however.)

Every single PCE I've modded in this way is also modded for RGB with a full amp circuit. The amp is placed in between the ribbon cable. I don't use a board for that either!

    Wait- are you really using the full circuit, or are you using this simpler circuit? Because that thing's becoming a nightmare to wire up even with perfboard and I'm thinking of trying the simpler one.

Full circuit.

I have this crazy obsession with designing configurations for mods crammed inside of cables and stuff and my mod design for pce I figured fit nicely flat in between the ribbon cable. The perfboard isn't cheap when you don't get a lot of orders so I keep my PCE mods down to minimal parts, most of which I use in other stuff.

Now I made this weird mod config that my family says looks like a windcatcher or something and my fiance says looks "retarded." IMO it is also way less ime consuming to wire up than perfboard. No linking all those contacts on the bottom of the board. As an alternative I cram all the parts inside of the SCART cable.

I have a pic of the SCART variant, I'll show you.



Hard to not get interference there but I cracked it.

There is, of course tape/heatshrink around the components in the DIN once it goes together, this is just to demonstrate how they go into the DIN.

I got some glue on that resistor in the DIN, it's accidental but I couldn't be bothered wiping it off and let it just set that way. TBH resistor needn't even be there, I was messing around with variants on the mod.

I will probably pour glue inside of that DIN in future as if you squish it, the legs on the caps could touch. Now it's hard to add heatshrink to 100% prevent that, and the DINs aren't as solid as a SCART plug. I sent one of these cables to Duo-R sans any glue as if it gets squished I'm sure he can fix that. And this is the amp in cable I am going to sell if anyone is interested.

I want to try to cram an AD724 s-video circuit inside of a SCART cable too, I am going to try.
