        The MicroVAX 3500 and MicroVAX 3600 were introduced as the higher end complement of the MicroVAX family. The new machines featured more than 3 times the performance of the MicroVAX II and supported 32 MB of ECC main memory (twice that of the MicroVAX II). The performance improvements over the MicroVAX II resulted from the increased operating speed of the CVAX microprocessor (90ns) plus a two-level, write-through caching architecture.
