Maybe someone can correct me but I thought the the speed should match the speed of the processor? Shouldn’t they be 16mhz/16mhz?
Nope, see the datasheet for the MC68882 (specifically page 5-98/PDF page 3). The CPU and the MC68882 work fine together at different clock speeds.Maybe someone can correct me but I thought the the speed should match the speed of the processor? Shouldn’t they be 16mhz/16mhz?
If you look at my screenshot from MacBench, you can see the results for two frequencies (@16M and @40M; the CPU was always at the default 16M). 40M gives a slight boost to the benchmark score. The card itself has a jumper to configure which clock to use (OSC means the oscillator on the card, SYS is using the C16M signal from the logic board which is 16M).Thanks, I remember some processors used to be really fussy about that. I’m glad this allows for flexibility.
I realized I still have two units of my original batch that I planned to sell (but the thread disappeared in the forum crash) - if you're interested just shoot me a PM!Any good place to get one of these assembled? A Classic II recently came into my possession and I'm interested in giving it toys, but my soldering skills are pitiable.
