Yes, an 8080, which sets the time frame for when it was developed.
Later models used a 8085
The biggest hardware innovation was smooth vertical scrolling, and
switching between 80 and 132 columns.
I remembered wondering if they got the idea from a letter to the editor
in either Byte or Dr. Dobbs where someone wondered why video terminals
scrolled a whole character at a time.
I've never liked the feature, because when you look away from the screen
the room looks like it's moving downward. Maybe that's why other company's
terminals let you set the smooth scroll rate.
