Well, it may not be foolproof, but on my home and work Zeniths, there
is a BIOS signature.  If you go into DEBUG (or the Zenith built-in
debugger) and enter

df800:0

you will get a dump of part of the BIOS.  On this machine, the dump
begins

07/17/84 (C)ZDS
CORP   

indicating a Zenith Data Systems machine.  You could search for such a
signature in your program.
