Does 470 Ohm seems reasonable for the LEDs on the left hand side in this diagram?
A typical LED draws around 20 mA, so this should give 9,4 V. But the Z80 is driven by +5 volts.
What resistor value should I use?
Also why is "E" used instead of "Ohm" in this diagram? After googling this it seems it simply means Ohm, and that "R" also means the same.
E -> R -> Ohm, are all equivalent (correct me if I'm wrong).
