Awesome job Mark thank you for adding those, I will now treat all address lines on pinouts as A'n' and not a specific number, its greatly helped my understanding.

Pin details on the CPU will always be correct.
With most systems, pin details on ROM chips will be correct.
The pin out for the ZX81 ULA is (I hope) correct.

It's just RAM chips on the Zeddy that you have to watch out for...
