Maybe someone else will have some more in depth knowlege. >the 11/23, 11/23+ and 11/24... I'm not sure about the differences of the 23 and 23+ but if you have a choice get the 23+. The 24 is Unibus the 23's are Qbus. >the 11/44 and 11/45... The 44 has split I&D, and Unibus map. The 45 does not. >the 11/70, 11/73 and 11/84/83... The 73 is a J11 chip set replacement for the 70. In other words a 70 on a chip. Also is a Qbus. The 84 is the current product line replacement for the 70 (Unibus), the 83 is the Qbus/J11 version of the 84. Mike Ewan Tektronix Inc.
