Regarding smearing with long-persistence phosphors--

One of my most pleasant experiences with a terminal was on an Adage
vector graphics unit programmed to emulate a TEC terminal.  It had 35
lines by 132 characters, a long persistence phosphor, and a DMA link to
the computer.

The relevant part of all this is that it did a lot of smearing.
Requesting the next screenful of data gave the illusion of the old
screen fading out and the new screen fading in, with the actual
scrolling completely unnoticeable.  Far from being objectionable, I
found this an extremely pleasant way of doing the job-- much superior
to any slow-scroll terminals I've seen.
