But if you
want to actually run them turned on when they are even two
high, other than a VT100 (which is what I still use for the first level), I
have not found another terminal (except for VT100 clones) which allows
stacking. In general, I use 6 terminals with 3 VT100s as the first level
Oh, VT52s (and similar), H19s, Most Newburys, some Beehives, etc all have
flat tops and can be stacked. And that's just the ones I have here...
Incidentally, the IBM PC monitors (5151, 5153, 5154) all stack pretty
well for storage...
