However, I see that the [http://www.bitsavers.org/pdf/dec/dsa/hsc/EK-HSC50-UG-002_HSC50_Users_Guide_Aug84.pdf HSC50 User Guide] calls it the "HSC50 Mass Storage Server" (Preface, pg. v). So, several DEC documents about the HSC50 disagree about the 'Controller'/'Server', but do agree on the 'Mass Storage'!
		+	: To add to the confusion, 'Controller' would seem to be preferred from the name, "HS'''C'''" - but if we are to rely on ''that'' as a guide, then we should go with 'Hierarchical'!!
		+	: Do you know of any DEC documents that give the formal name of the HSC50 to be 'HSC50 Hierarchical Storage Controller'?
