Have you tuned up your H316? My machine is running on 1.6us! In that 
case I would be glad to get your CPU and memory timing configuration :-)

(Otherwise it would be an interesting experiment to see if and how much 
faster a H316 could be made. I'm quite confident that Honeywell/3C 
delivered the machines in a very stable configuration with big reserves 
with respect to reliability)

Best wishes,

Philipp :-)
