I recently picked up a "new" machine, Asterock (Asteroids bootleg) and did some first basic checking of the PCB and noticed the crystal was loose (broken). Schematics say 12.096 Mhz crystal. Original Asteroids also has a 12.096 Mhz crystal, but all I see available today are 12 Mhz crystals. I know the frequency is divided down to 1.5 Mhz for the processor to run on. I think the difference in timing will be hard if not impossible to notice but what do you guys think ?
 
The difference is going to be so incredibly minor that you'd be hard pushed to notice it. Use the 12MHz xtal, it'll be fine.
 
Good find. They deliver here too but....18 euro shipping costs.... :S
(I'm in Europe)

That's what I love about RS online, no shipping costs and local stock. But they don't have the 12.096 Mhz crystal...
