Hi everyone,
I've got a Motherboard with a PQFP-132 AMD 386DX-40 and a socketed DIP-14 80MHz oscillator (originally zip-tied). I've purchased a batch of 66.6666MHz and 50MHz oscillators with the intent of being able to adjust the clock frequency to 33.3333MHz and 25MHz for games, specifically the notoriously speed-sensitive Wing Commander.
My questions are:
Other than changing the oscillator, for a normal 386 motherboard would anything else be required to get the CPU and motherboard to clock down?
Is the motherboard able to detect the frequency at which the CPU is running and/or its designed frequency?
I can post pictures of the board tomorrow or the day after, if needed or interested.
