The 2250 MCS console support was flaky; I once crashed something (38 years later I can't remember if it was just the 2250 or all of MVT) by idly clicking the light pen aimed at the fluorescent lights in the ceiling. Interestingly enough, MVT supported using the light pen to click on the MCS console for the functions of "K D,F" and "K E,D", and I have a really vague recollection that there were numbers you could click on for the equivalent of PFK-assigned commands.
When we got our 360/165, my first impression was that the 3066 console looked like a stripped 2250, complete with a cursive character set, and minor flickering. I wrote code to run it with EXCP, and was impressed by being able to use a mixed Read/Write CCW chain that preserved user input while updating the screen outside the input area, and no keyboard lockup.
