What kind of computer is this?

This was one of those, 'oh, it's got 5 sec left, I'll bid it up five bucks, I won't win, and then I won' situations.  It's a Z80 single board computer, it just arrived, so here is some raw footage of me messing about with it.  This is the kind of surface level exploratory stuff I do with incoming vintage gear, especially homebrew stuff like this.  What did the builder intend for this? Sadly the EPROM appears to be pooched.  I'll post the garbled code below - let me know if you recognize anything in it!
