Technical summary - OpenVMS on VAX

The following technical summary is intended to help you understand some of the key aspects that you will come across when working with a VAX system.

VAX hardware overview

VAX console interface

Each VAX implementation had its own specific console interface. In general they are fairly consistent between models, certainly for the later mid-range VAXes based around the N-VAX chipset (3100s, 4000s).

Early VAXes generally had a PDP11 acting as a console subsystem.
