The 5252 was 2 CRT's back to back. It was one big box with 2 screens and 2
keyboards, and heavy as all get out.
One had to hope one's co-worker was not annoying. :-)
A cool thing about those 5250 terminals was the test switch, where you could
see the invisible parts of the data stream. It made coding the right hex
characters for the attribute byte pretty simple. I think there was a chart
that translated the hex to the attribute byte. That was many moons ago.

Then you'd be the person to ask these questions:
1. Is it true that the earliest 5250 data stream terminals had panel
lights instead of a status line?
2. Did any physical terminal have the type of "alphabet soup" status
line seen in WSF and RUMBA?
3. What was the 5252 really like?
