# Memory Decoding logic
|
||
|
|
This folder contains the memory decoding logic used by Pat80.
|
||
|
|
The memory map is a simple 32k ram / 32k rom obtained using the MSB as EN signal.
|
||
|
|
The I/O space is split in 8 devices (each with 32 registers).
|
||
|
|
Pat80 doesn't use the [high address lines I/O hack](https://retrocomputing.stackexchange.com/questions/7782/z80-16-bit-i-o-port-addresses) but adheres to the official Z80 I/O documentation.
