Hey Cosmos,
Do you have experience setting up external oscillator on A3630 with different frequency then 25MHz?
I tried to use 40MHz osc.with 40MHz FPU (I got on Ebay some time ago) on that board and it fails to work, I'm pretty sure jumpers are set correctly.
Another oddity I find is when I use 25MHz external oscillator, the FLOPS measurement is lower then using A3000s FPU, weird.
Any tips?
I have to use that board on my A3000 because onboard 68030 is dead.
