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 two-phase
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 wiresonic
delay lines.
That was the Super Bee, right? 8008 CPU, but I thought the memory was
MOS shift-register, not bucket-brigade (which I mostly associate with
analog applications, such as reverb effects).
I had one of those Beehives. Nice big heavy terminal with offline
page-edit capabilities.
