8275 - think Wyse 50 terminals.  Doesn't use a dedicated buffer, but 
DMA to do buffer refresh.  Attributes (e.g. bold, blink, etc.) use a 
space on the screen, unless "invisible" mode is enabled, in which 
case each line occupies a variable number of bytes and a maximum of 
16 attributes per line.  7-bit character set.

I learned to hate the bloody thing.
