			I question the following unsourced statement:
			"The PDP-9 established minicomputers as the leading edge of the computer industry."
			I hardly consider the 9 a minicomputer and it had little impact on the computer industry as a whole. If any DEC product deserves this acolade, it would be the PDP-8, but we'd need a source.—[[User:ArnoldReinhold\|agr]] ([[User talk:ArnoldReinhold\|talk]]) 09:22, 21 November 2018 (UTC)
