Idle Trivia.
Kaypro used Z80 and then switched to 8088 in their first DOS machine. Have
schematics somewhere for it.

<snip>
An 8085 cab be upgraded to an 8088 and use the same hardware and chipset as
the 8085, but when you do this, you cannot use an 8087 co-processor. Kaypro
and some other manufactures put both processors in thier systems, the 8085
and 8088.
