Ice Final with Crystal oscillator help
Ice Final with Crystal oscillator help –
I have all the parts to build ice mod but i can't find resonator around where i live, so i bought a 50Mhz Crystal oscillator(SG531PH).
Can anyone please tell me how am i to replace the resonator with the crystal oscillator i bought. I have a V4(30001) US set.
Using Non-R code.
Help is appreciated.

You link pins 1 and 14 of the crystal oscillator to +5V, pin 7 to GND and pin 8 to the OSC1 pin of the SX28AC microcontroller (pin 27). The OSC2 pin (26) must remain unconnected. The resistor between the OSC1 and OSC2 pins must be removed.
For reprogramming of the chip you must disconnect the link between pin 8 of the oscillator and the OSC1 pin (27) of the SX28AC. After programming you must do the link again. If you can, put two solder points close to eachother so as to break the link by removing the solder bridge between the two when needed.
Emanuel explanation is right
I tried, but failed maybe my wires are too long as i built with breadboard and route the wires to the external.
I will try to shorten the wires and see how it goes, thanks.
Final Ice not working :(
Final Ice not working :( –
I followed the instruction for the crystal oscillator and uses http://d-vices.com/subzero/s02-4.jpg for the points(all points used except C,D,H and 3.3).
But nothing is working, like unmoded PS2, original boot ok but not backup.
Can you please help me verifiy if the diagram(modified to use sg531 crystal oscillator) is correct?
Your schematic is OK, except the B and F points. They must be swapped, like in the attached schematic.
Thanks again! Will try it later when i get back
Thanks guys! Its working perfectly now really thanks alot
