TurboExpress/PC-Engine GT Screen and A/V Out Boards

[MobiusStripTech]

Hey Guys,

I made a couple small PCB's and put them up on OSHPark for anyone who wants to order them. These are based on thesteve's circuit for modding your TurboExpress or PC-Engine GT for a new screen or A/V Out. While the circuit can obviously be built without these, I just think it's a bit cleaner than using perfboard or building a circuit on top of the 6260.

Just a note, I have now installed these and can confirm they work just fine. It definitely helps keep everything clean.

Yeah I can sell you prebuilt ones if you want. Do you want the ones with or without the AV out? The circuit is slightly different if you want AV out or just a screen mod. I can give you some instructions as well. All of this is based on the circuits and findings that theSteve posted on here. I just made a board to contain the circuit.

You will still need to lift the pins on the huc6260 and obviously make those connections. Just let me know which boards you want.

I would like the prebuilt 2pcs  that will do both LCD and AV out

How much for 2 pcs ?





Thanks

Hey MobiusStripTech,

I got your package.. Thank you!

The two pics you posted , the first one is showing the pins of the chip that needed to be lifted and they all
need to be grounded to same wire?

And what’s the second pic for? 

Thanks

Just a potential mounting point. You can put them pretty much anywhere you want because they are so small.

The pins that need lifting can be individually hooked to ground or you can hook them all together and then to ground. The latter is easier.

Thanks for that Keith.

RxM, that is the circuit schematic these boards are built from. So basically just lift and ground all the pins listed at the top of the schematic. Then connect all the other pins listed to the appropriate points on the board. Then you are good to go.

Thank you MobiusStripTech & Keith Courage.  Your help greatly appreciated.
