I'm a long-term microvax3900 SIMH user, and tried the 4000/60.
Installation works, but after reboot:

That's not a perfect configuration, but ... anybody has a specific
clue what prevents it from booting?

Not too bad. But ISTR that the real /90 and /60 both hat quite stable
frequencies at about 37ish or so, here it's higher... I'll let it run
for some time (with NetBSD idle detection) and see what happens.
(Maybe idle detection plays a role, too. Just sayin'.)
