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...
