 It's very wierd, it's the only ASCII terminal that I've seen which is a
 portrait-mode terminal!  Is this some kind of VT-100 compatible or
 something?  The only thing I've ever seen that even comes close is some of
 the old Macintosh monitors. 
It's probably a flavor of the Ann Arbor Ambassador terminal.  I
remember them as being in somewhat widespread use by Unix folks in the
early-to-mid 1980s, their major feature being the number of lines of
source you could fit on the screen.  They pretty much fell out of
favor across the mid-1980s with the proliferation of bit-mapped
displays.
