	Would it be correct to say the uVaxII was supplied in both
	size cases, while the Vaxstation II was BA23, and the
	Vaxstation II/GPX was in a BA123?

	Many thanks... details noted :)

	How many Q-bus slots were in the BA123? (and BA23 for that matter)

	Would you know what the actual PSU ratings were?
