'T.S.T.' - early Apple clone? Help!

[Barton Oleksy <boleksy@nait.ab.ca>]

I just picked this up yesterday thinking it was an early Apple model,
but now I don't think it is.  There were two Apple stickers, but the
only 'permanent' marking is a metal plate above the keyboard that says
'T.S.T.' within a blue diamond.  A pile of 5.25" floppies were included
that all look like Apple software, and it ran all of them.

Upon bootup, there's a brief message at the top (center) of the screen
saying 'T.S.T.' as well.  Once in a while (depending on the diskette) I
can get to the ']' prompt, but most commands I've tried don't work (like
CATALOG).  All I could get it to do was with the short-hand PRINT
command ('?') to print back to the screen 'hello'.  (exciting, yes)

Also, holding down the Control and Esc keys dumps out 10 variable values
of some kind.

Any help identifying this puppy?  Know any background info?  Thanks!
