	IIRC the MicroVAX I is probably the least of the VAXen - 1/3 the
	speed of a MicroVAX II, maximum 4MB of memry, and (most important)
	without a full implementation of the instruction set. (It has to
	emulate some of the lesser used instructions). There are probably
	other differences as well.

	Having said that it should be possible to port NetBSD to the
	machine given the right docs. You should be able to modify gcc to
	only use uVaxI instructions given an appropriate flag, or
	implement the extra instructions in software as I believe VMS did.

	If someone wants to try a port to this box I'm sure there are
	people willing to help :)

	Incidently (question to the list). Are the 11/730 / 11/725
	limited in a similar way to the uVaxI? Would a port to one help
	the other?
