Notes on System Models

Starting in the mid-late 1980's, most VAX systems were based on VAX microprocessors (the exceptions were the VAX 9000 and all VAX 8xxx except for the VAX 8200/8300 series). The microprocessors were:

VAX-11/780 Systems

CPU-specific support for the VAX-11/780 family of systems originates from 4.4BSD, and was modified for NetBSD by Anders Magnusson.

Supported Hardware

The VAX-11/780 family is Digital's oldest VAX product, it was initially announced in 1977. It includes the following models:

VAX-11/780-family systems may include none, one or more of the following hardware:

NetBSD/vax does NOT support the following hardware on 11/780-family systems:

Because of lack of time and hardware to test and develop on, support for these unsupported devices are unlikely to ever be written.

NetBSD/vax also supports devices that can be connected to both the Unibus and Massbus, as described on the Massbus and Unibus hardware support pages.

Known Bugs for the VAX-11/780 port:

VAX 8200-family Systems

CPU-specific support for the VAX 8200 family of systems originates from 4.4BSD, and was modified for NetBSD by Anders Magnusson.

Supported Hardware

The VAX 8200 family was announced in 1984. It was the low-end of VAX systems to support the new BI bus. The family includes the following models:

VAX 8200 family consists of a generic BI bus in which one or more CPU are located. The only VAX 8200-specific device is a RX50 floppy used as console media.

NetBSD/vax also supports devices that can be connected to the BI bus, as described on the BI bus support page.

Known Bugs for the VAX 8200 port:


MicroVAX II and MicroVAX III Systems

CPU-specific support for the MicroVAX II and MicroVAX III systems originates from 4.4BSD. MicroVAX II was ported to NetBSD by Rick Macklem, and MicroVAX III was ported by Anders Magnusson.

The MicroVAX II was based on the first one-chip VAX, the 78032. It was the successor to the MicroVAX I. In fact, at the time the 78032 was the first 32-bit microprocessor with both memory management and floating point on a single chip. MicroVAX III was the successor of the MicroVAX II and was based on the CVAX (2nd generation) chip.
