The FPS T-Series used VRAM from TI for program and data memory for each
vector node.

The video-rate shift register ports on the VRAM were connected to the
vector hardware; the "ordinary" parallel port was connected to an 
INMOS T414-15 transputer as external memory.

The T-20 had 16 vector nodes, each with their own private 1MB of VRAM.
