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? Tony. -- f.anthony.n.finch http://dotat.at/ The Minch: Southwest 5 to 7, occasionally gale 8 for a time, decreasing 2 or 3 and becoming cyclonic later. Moderate or rough. Rain or showers. Moderate or good, occasionally poor.
