It's been awhile since I owned a couple of SuperBees, but they used
welded-aluminum slab-sided cases and not the fiberglass one shown in
the photo. The whole front CRT area was covered with a sheet of
brown-tinted acrylic, held on with velcro-ish plastic fasteners. The
keyboard itself was parallel output ASCII and had two shades of beige
for most keys with yellow special-function keys. Several keys had
little round "windows" illuminated by bi-pin lamps. The keyboard
case could have been aluminum, but might also have been die-cast zinc-
-I don't recall, except that it didn't have the sharp corners the
main unit did.
The SuperBees were page-editing terminals; you could shoot a page of
text to it, edit it offline and then hit TRANSMIT to send the text
back to the host. It was also possible to get the terminal into a
state where you needed to cycle the power to get it out of some
unresponsive condition. When transmitting a page, 1F (hex) was used
as an EOL character.
CPU in these was an 8008 with shift-register storage.
