|The heart of the 6000-600, the
NVAX chip, built using 0.75 micrometer CMOS technology was the strongest
CISC (complex instruction set computer) processor of the time, with a performance
that was comparable to RISC processors. A one-CPU 6000-600 had a performance
of 32 VUPs.
Several MicroVAXen and VAXstations were also based on the NVAX chip, like the VAX 4000-500, -600, -700 and -100, and the MicroVAX 3100 Model 90.
OpenVMS: Digital parted with its previous policy of mostly implementing proprietary technologies, and modified VMS according to POSIX standards.
DECnet phase V: Another big move by Digital to open DECnet for OSI standards and TCP/IP.
