NEO-E0

System ROM vector table swapping
When 68k A8~A23 = 0 and the System ROM's vector table is chosen (by using or ), A22I~A23I outputs are set to 1. This makes the address appear to address decoding chips as a system ROM access instead of a P ROM access.

User:Kyuusaku: {A23Z,A22Z} = A[23:22] ^ 2{~|{A[21:7],^A[23:22],VEC}}

On the AES, the AND gate is used for /SROMOE from /SROMOEL AND /SROMOEU.
