The '''VAXserver 3500 and 3600''' are variants of the [[MicroVAX 3500/3600]]. The difference between the 3500 and 3600 is unclear (both used the [[BA213]] enclosure, and had a 12-slot [[backplane]]).

Both used the [[KA650 CPU]]. The [[QBUS]], which both are built around, was used only for [[input/output|I/O]]; [[main memory]] used the [[KA650 Main Memory System]], using a special [[bus]] carried on [[over the back]] connectors as well as the [[CD interconnect]] of the QBUS backplane. (The [[address space]] of the [[QBUS]] was limited to 4MB, and the data section is only 16 bits wide.)
