Digital VAXstation 4000/60

The VAXstation 4000 model 60 was announced on the 30th of October 1991 and became available on the 25th of November 1991. Its codename was "PMariah" and uses a KA46 CPU module containing the Mariah chipset operating at 55MHz with 256K of external cache. It was the first VAX to use TURBOchannel. VAXstation 4000/60

This one lived at GNS Science in Lower Hutt until the 20th of December 2008. The system is in good condition and runs well. At 55MHz the VAXstation 4000/60 is a fairly quick VAX. Its built-in ethernet and SCSI also makes it much easier to work with than older QBus systems.
