I was scrounging around for anything I could find on Crystal Oscillator i still don't know what I need to pass to get a stable frequency out, I was trying to send the out from a 555 doing as many cycles as possible feeding the out to a crystal of 3khz it just did not seem to be working at all, so once i work out how to use one properly in a circuit....
Anyway while looking, It turns out a lot of the older computers, gameboy, some calculators, sega, N64 etc, just by changing the frequency of the CPU it runs at, so if the CPU had a 30mhz crystal, you could replace it for 60mhz, doubling the clock speed... now here's what I don't get, what is the limit? I remember my old 486 pentium 33mhz with 4 meg of memory, it did not require a heatsink or fan at this point in time although a heatsink was probably a good idea!
Now, if I decided to change say the 33mhz crystal in small device like a gameboy or faster, what's my limit to how much of an overclocking i can give the CPU? (sounds rude lol)
Could i got 200mhz could I stick my existing HeatSink and Fan (2.8gighz) and get a crystal of say 900mhz or even 1000mhz would that cpu which is designed for only 33mhz be able to cope providing 1000mhz if it was cool enough?.. and seriously to get a device which is only 7-8mhz like a gameboy what was the reason for not using a 20mhz crystal give it some kick?... the only thing i can think of is battery life... it seems to me games could have been a lot more fun on even quite outdated hardware simply by increasing the frequency and not having to worry about heat???
