 NEC and DEC but never Datapoint. 
Darn--I've wondered about a design link between Datapoint and Beehive
terminals.  The Beehive design resembled the Datapoint more than
trivially--it used no static ram, but rather dynamic shift registers as
screen and working memory for the 8008.  Since that was a pretty formidable
design for its time, I wondered if Beehive had recruited Datapoint talent
to do it, since DP would have had the best knowledge of the wiorkings of
the 8008.

That was technology of the era. hasiltine H1000 and H2000 terminals
and I think the VT05(hard memory test) did as well. Static rams were 
expensive and small and since screen ram was by nature circular as 
part of the raster scan it makes sense to keep the whole mess as 
shift registers.

Never worked much with terminals printing systems were more my thing.
