Way back in the dark days (1976 or so) I cloned a Beehive 
CRT terminal.
It used silicon bucket brigade memory (CCD).  they had a 9V 
clock, and just a bunch of charge storage spots and the clock
pulses peristaltically shifted the charge packets down the line.
This was VERY much like earlier terminal designs that used 
delay lines.
