He can get a login on a real CRAY YMP-EL 98 for doing compatibility
tests: http://www.cray-cyber.org/
Would be interresting to see how he emulates the I/O system. Either he
has to emulate the VME I/O processors and run the real Cray "firmware"
on them or he has to reverse engineer and reimplement the protocoll main
CPU <=> I/O processor.
