there was
some CP/M software that required z80. However from a
business user
perspective most of the deireable and likely used software like word
preocessors, spreadsheets and databases 8080 was just fine save for
speed and the 8085 solved that. Also the 8085 was more of a bridge
than the ultimate application cpu.
We ran into a few vertical apps that required Z80--and I think one of
the better word processors (maybe a late Spellbinder?) required a
Z80. BASIC dialects were different enough back then (and today) that
an application written with a specific Z80 BASIC in mind would get
you into trouble with an 8085.
It wasn't enough to make us consider developing a Z80 card, since we
were marketing our own OS and applications anyway. But I'm certain
that the lack of a Z80 cost a few sales.
