Someone in Sweden wants me to mod a US Turbo Duo for RGB on a euro PAL TV. No, I don't think he has NTSC capability, so that isn't an option.
Do I need to change the crystal for even the RGB to work in europe? Does the composite sync matter for that? I assume the answer is yes for all this.....
The PAL TG16 used a sony CXA encoder and the appropriate circuitry to make PAL compatible output. I haven't fired it up but I imagine the system was underclocked to 50Hz. The PCE video chip does not natively support PAL rates or encoding, a surprising omission for such an otherwise capable chip.
Yeah, but this dude wants a Duo. I guess I could mod a PAL TG16 (got a couple here) and sell him a CD add-on. Not a very glorious solution though.
Well the reason I bring it up... The Duo IS a TG-16. There's no difference in any of the main chips - the CPU, graphics or video - between the Duo and the TG. What works for one will work for the other.
