Hardware Documentation - Machines DEC - VAX hardware reference
This is an (incomplete) list of Digital Equipment Corporation VAX computers and specifications. Compiled by abs@NetBSD.org with much help from port-vax@NetBSD.org users. This is very much still a work in progress - many sections are little more than placeholders. Having said that, there should be enough here to prove useful. |

---|---|---|---|
Vup: | 1.0 | Tps: | 8 |

NetBSD: | Can run NetBSD | Last updated: | 2003-07-18 |
Notes: | Earlier, slower version of the VAX 11/785. First VAX |
VAX 11/782 (VAX 700 series index)
Nickname: | Atlas | Cpu: | Dual KA780, 78032 (200ns), 8KB on chip cache |
---|---|---|---|
Vup: | 1.8 | ||
Bus: | 2 SBIs with 15 nexus slots each. Each slot can take a UBA (UNIBUS adapter), MBA (MASSBUS Adapter), or CI. (?) | ||
Introduced: | 1982 | NetBSD: | Probably |
Last updated: | 2003-07-17 | ||
Notes: | ASMP dual CPU system comprising two VAX 11/780s connected via a (MA780?) 4Mb shared memory cabinet. Apparently faster when split back into two VAX 11/780s. |
VAX 11/784 (VAX 700 series index)
VAX 11/785 (VAX 700 series index)
Nickname: | Superstar | Cpu: | KA785, <785> (133ns), 32KB on chip cache |
---|---|---|---|
Vup: | 1.5 | ||
Bus: | SBI with 15 free nexus slots. Each slot can take a UBA (UNIBUS adapter), MBA (MASSBUS Adapter), or CI. | ||
Memory: | Maximum 512M (theoretical) | Enclosure: | 153*118*76 cm (H*W*D), 498kg, 6225W |
Introduced: | April 1984 | Image: | VAX 11/785 |
NetBSD: | Can run NetBSD | Last updated: | 2003-07-18 |
Notes: | Later, faster version of the VAX 11/780. The final machines in the 11/7x0 range would have been the 11/790 and 11/795, but were renamed the VAX 8600 and VAX 8650 respectively. |
VAX 11/787 (VAX 700 series index)
Nickname: | (?) | Cpu: | Dual KA785 '780' |
---|---|---|---|
Vup: | (?) | ||
Bus: | 2 SBIs with 15 nexus slots each. Each slot can take a UBA (UNIBUS adapter), MBA (MASSBUS Adapter), or CI. (?) | ||
Memory: | Maximum 512M (theoretical) (?) | NetBSD: | (?) |
Last updated: | 1998-01-28 | ||
Notes: | If it existed at all, it was two VAX 11/785s connected in an ASMP system. May have been sighted in Australian Defence Department |
