There's also the NEC PC-8201 and PC-8300.
These were all built by
Kyocera. Olivetti also sold at least one machine built on that design,
but I don't know the model number(s).
The Epson HC20/HX20 (the HC was a different color, and also had katakana
on the keyboard and in the character generator ROMs) was a 6803?, smaller
screen, microcassette "drive", etc.
Not as well suited for general purpose use as the Kyocera machines, but
with the addition of a cash drawer made a helluva cash register.
These are all larger than a Z88, though. I think
the "no larger than
a Z88" requirement will make this pretty much impossible. The Z88 is
pretty tiny.
The smallest machine of THAT vintage was the Epson RC20 (wristwatch
computer). Z80 like processor, RAM, ROM, and a serial port. NOT
imported into USA.
