The '''VAXstation 3200 and 3500''' are members of the second generation of [[VAX]] [[VAXstation]] [[workstation]]s; they differ only in their enclosure, the size of their [[backplane]]s (and thus in the number of slots available), and in the [[peripheral]]s that come pre-packaged in them.

Both are built around a [[QBUS]], used only for the [[input/output|I/O]] [[bus]]; they use a special bus carried on [[over the back]] connectors as well as the [[CD interconnect]] for their [[main memory]] bus. (The [[address space]] of the [[QBUS]] was limited to 4MB, and the data section is only 16 bits wide.)

Both the 3200 and the 3500 use the [[KA650 CPU|KA650-B]] [[Central Processing Unit|CPU]]. Commonalities and differences of both types of workstations are listed in the following table:
