The MicroVAX 3500 and MicroVAX 3600 are very similar; the only distinction appears to be the enclosure: the 3500 was available in the BA213, and the 3600 in the H9644 cabinet.
They used the KA650 CPU; 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 QBUS was used for I/O.
