So, I've been thinking.

In order for me to recoup my RC2014 Zed investment1 , I'm thinking I might want to build my own 65816-based CPU card for that backplane, and just map the 64KB of Z80 I/O space and memory space into 65816 "I/O space.2 "

________
1. OK, let's be honest; my *wife's* investment, for she bought it for me for my birthday during COVID lockdown.

2. The 65816 does not have dedicated I/O space; but it does have a 16MB address space broken up into 256 64KB "banks" of memory. I can just devote two banks to "backplane" space.
