The VT05 needed a delay added on CR as it was slow to scroll the
screen buffer, so every logon would have required: stty cr3
I amused to see that stty cr3 still works on Linux but on my desktop
there is no visible effect on scrolling speed.

I suspect the VT05 was not popular as it was slow, uppercase only, 72
characters x 20 lines, and not cursor addressable (much like Teletypes
of that time). I also think the VT05 never sold in significant
numbers, certainly to this day there are only a small number in the
hands of collectors (despite being much sought after).

This caught my eye: "It is completely portable, weighing only 55
pounds...". The VT05 is a beast, it is so deep (Depth 76cm / 30
inches) and heavy, although one person could lift it, the size and
shape really make it a two person lift.
In searching for images on the Internet I'm not finding as many images
of DEC PDP-11 installations from the 1970s as I hoped, mostly the
usual DEC marketing photos. This suggests a todo item is to compile
photos of early Unix installations sequenced in time.
At my local university I recall the early CRT terminals connected to
Unix systems were: GTC GT-101, ADM 3a, VT100  and Tek 40xx. The
first CRT as output displays (these arrived before the terminals) were
Matrox graphics card connected monitors.
 The DEC VT100 was rare as it was expensive at the time and the
usual reason anyone had one was it shipped as the console bundled with
