That was my understanding too. I remember seeing it on a DEC price list after the Mentec transfer, as a class L license only (Q-bus, no Unibus), and for a crazy high price ($20K-$30K IIRC). Which kind of lent value to the rumor I'd heard at the time: that DEC withheld IAS from Mentec because there was some particular high-value customer still buying it, and DEC wasn't yet tired of taking their money. The single choice for the license made it sound like there was only one config still in play (i.e. whatever that customer used). Yeah ... John Wilson D Bit
