Everyone knows that the perfect capacitor to decouple the power rails around ICs is a 100 nF ceramic capacitor or equivalent, yet where does this ‘fact’ come from and is it even correct?

My takeaways from these, were that: CS should be asserted a little before IORD and IOWR The data line transitions should be limited, either via 100Ω resistors (good), or a 74x245 bus transceiver ...
