IT was a reduced capability machine. You¹re thinking of the rtVAX, which was a different product; the rtVAX 1000 was a MicroVAX II, but without memory managent. It could not run VMS for that reason, but ran VAX/ELN. The removal of memory management made the system more deterministic for real-time purposes. Camiel
