I know that back in the day, we had about a dozen VT52 and 3 VT50's.
They were the same keyboard, but with different internal circuit
boards (we had a few former VT50's that were upgraded to VT52's, at
least according to the techs that I worked with at the time). I still
remember having to edit my FORTRAN code for a while on a UPPERCASE
ONLY terminal until I got enough seniority to warrant moving up a
dual-case terminal.... thankfully these were all replaced by VT100s
over the years I worked there and my role shifted a bit to needing a
VT100 to support a customer that had an application that used the
advanced features of the VT100: double size characters, line drawing
boxes, etc.

Man, that was a million years ago...
