Look up the documentation to PAR: device or bang the Paula chip. You won't see special In/Out assembler opcodes on any other processor than the Intel due to patent issues.
The Z80 (and I believe a number of old 8-bit processors) had I/O ports. I/O ports are really a relic from the days of old when you needed the entire memory range for actual memory so the devices had their own memory space of sorts. With more modern processors that supported more RAM the idea of having a second memory space for devices became an unnecessary complication.
