I have an urgent WTB item!

I'd like to ask for one little specific electronic element - a "quartz resonator/oscillator" at EXACT 21,31250 MHz frequency (can be new or used, doesn't matter), the exact freq. is essential here. This quartz in particular is being swapped with a different one during conversion or modification process in some of the Famicom version consoles (I believe the HK ones).

I need this quartz for my new project and believe me - it is impossible to get it here in Poland, I've tried everything and everywhere (even asked gamedoctorHK and JGS) but unfortunately with no luck. I'd be totally thankful for someone to get me one of those. BIG THANKS in advance for any of you for helping me out.

I'm ready to PayPal pay for it + shipping.

That's it. Sorry for my poor english skills.
I'm waiting patiently for answer.
Regards and Take care.

I have a HK FC w/ one, but I'm not sure I'm willing to sacrifice it for you :P What is your project? I can't imagine why you need it. The frequency is not standard, it was chosen because the pixel clock (21312500 / 4) / 341 (dots per line on a FC) yields the PAL line frequency of 15.625 kHz, not likely any other application uses it. If you're thinking of adapting a NTSC console to PAL, it's more involved, you need logic to halt the PPU/VDP (and blank/keep sync) an additional 50 lines until you achieve 50 Hz. In the case of FC, you also need a NTSC>PAL transcoder.
