Unless there
was an upgrade option for the VT52 I don't know about, the
'VT52' w/printer is actually designated the VT55.
Not according to my docs (and the unit I have coupled up to my 11/45)
The VT55 is a VT52 with a 'waveform generator' card. This is an option
for plotting graphs, roughly compatible with the VT105. Basically, you
can store 2 'heights' for each vertical dot-column on the screen, and
either display a point at that height (for plotting mathematical
functions) or all points below that height (for plotting barcharts). It
gave a reasonable resolution for this, with very little memory.
The electrolytic copier (wet paper printer) was an option for either the
VT52 or the VT55 (and maybe other VT5x terminals). Most VT55s had it
fitted. Most VT52s didn't. But all combinations were possible.

Thanks, I stand corrected. I guess I have just never seen a VT52 with the
copier, only VT55s. (Guess I had to be there... :-)
