Here is a system from the 70's.

The S100 Boards - 16 KB RAM, 8 bit 4 MHz Z80A Zilog Processor, Floating
Point Math, and Micro Disk Controller Boards

The Micro-Term Monitor and Keyboard

Ahhh ! those were the proper computing days..
But the Z80 was 16 bit (just sort of) not 8 .

QX-10 and Valdocs, have two of them in my attic next
to boxes of TRS-80 parts.

Ahhh yes. Fun to be a programmer back then. Life was so much simpler.

I don't pretend to be any sort of expert on the hardware end. I
fortunately have all the manuals (I don't understand them fully, but I have
them).

Figure 2.0-1 in the Z80 and Z80A Technical Manual shows an 8 bit data bus
and a 16 bit address bus. The 'registers' may be accessed as 8 bit
registers or as 16 bit register pairs. I guess that's what you mean by
'just sort of'.

Thanks for the clarification.
