Playing Clash at Demonhead. Apparently the music causes my cat to give me murderous looks and leave the room.
Hey guys, lets say I need to find the proper order of address pins on an unknown CPU. While addressing ROM, the address lines will count up sequentially in binary. If logic 1 is +5v and logic 0 is 0v, then can I find the ordering by measuring and matching each pin with a theoretical voltage?
Lets say Vt = (vRef)/(2^address)
vRef is the voltage that our vpp rest on, 2.5v in our case
address is the address pin from 0-12.
If we remove the ROM and allow for the address pins to ripple as they do, I believe the measurements will be:
2.5v
1.25v
0.625v
0.3125v
0.15625v
0.078125v
0.0390625v
0.01953125v
0.0097656250v
0.00488281250v
0.002441406250v
0.0012207031250v
0.00061035156250v
Is that correct, or should we start with address as being 1 instead of 0?
:grazy:
I've decided to ignore Jazz's post instead of showing my ignorance. Clever, isn't it? :wacko:
