Zilog did a nice BASIC, which they shipped in a

messed with, after having typed in the entirety of a faded printout of a
hex dump in order to get into digital form...that was tedious.
I got two of the first batch of Z8671 (BASIC in ROM) and Z8681 (ROMless)
in the UK, and built a couple of little boards along the lines of Steve
Ciarcia's. As Dave says, it's not at all like a Z80. It's a nice
architecture, but I never did an awful lot with it once I'd built the
boards. I remember that my Z8681 was a very early version and it came
with a sheet explaining that the reset didn't work as intended and how
to implement a hardware workaround.
