At the time, SRC was building multiprocessor research workstations with
VAX chips (the Firefly, I did some of the hardware) and WRL was building
an ECL RISC machine (the Titan).
I've found a Titan System Manual from 1988
https://www.hpl.hp.com/techreports/Compaq-DEC/WRL-86-1.pdf
It's a curious machine with a number of unusual instruction set features -
an 8 bit CPU process ID hooked into the virtual memory system, register
banks selected using the processor status register - otherwise RISC
flavoured. Did it have any successors?
