My high school got its first computers in 1986, a dozen or so Sanyo CP/M systems. Our teacher, who was as new to computers as we were, was overwhelmed with teaching everyone how to get a directory listing and use Wordstar, so he handed me some books when he saw I was bored. So my first programming experience was in Z-80 assembly.

The first computer I owned was a Commodore 128, about a year later. It came with a Z-80 and CP/M on disk. Unfortunately, I never really found anything useful to do with it that was better than what was available for the native 64 and 128 modes.
