From: Ron Natalie <ron at brl-vgr> Guess again guy, there is no such thing as a 22 bit UNIBUS. 23's have Q-Buses. 24's have unibuses. The 23+ was a documented processor with 22 bit addressing (those of us with plain 23's found that they were inherently 22 bits two and it was easy to make us of it. -Ron
