> I think it was a lot more common for 8bit systems to allow for 16 bit addressing though.

The 6502 and Z80 could use 16 bit addressing to access up to 64kb of memory. The 6502 had various other addressing systems, including iirc 8 bits, but none of them were wider tha 16 bits.

Oh yeah. I had loads of 6502 and Z80 systems (still do in fact). Can’t believe I forgot about that!

Though in fairness, I do mostly now just use those systems to teach my kids BASIC

Well, most of the addressing modes of the Z80 used a 16-bit register pair (i.e. 0 to 64K-1 bytes) to address, the 6502 used a somewhat stranger set of addressing modes, but once again you could address 0 to 64K-1 bytes.
