I got one a few years back. Such a unique machine! The CPU is 16-bit iirc, but the rest of the system is set up as 8-bit. And some kind of strange scheme with shared RAM that makes the whole thing ultimately very slow.
I never got too far into it since I didn’t have a disk drive for it. I hear there are kits available now, since the originals are somewhat expensive.
Yes! They were originally going to use an 8-bit CPU but had to change the design for some reason. It had 64k of addressable memory space, some of which was mapped to I/O and video and whatnot, I’d guess the memory scheme you’re talking about is how it took two clock cycles to read or write a 16-bit data byte on the CPU.
