3: # Notes on System Models
4:
5: Starting in the mid-late 1980's, most VAX systems were based on VAX
6: microprocessors (the exceptions were the VAX 9000 and all VAX 8xxx
7: except for the VAX 8200/8300 series). The microprocessors were:
8:
9: - 78032 -- The first VAX microprocessor started shipping in 1985.
10: About equivalent in CPU performance to the original VAX-11/780. In
11: fact, at the time the 78032 was the first 32-bit microprocessor with
12: both memory management and floating point on a single chip. It
13: showed up in many system including the MicroVAX II and the VAX 8200.
14: - CVAX - Achieved from twice to four times the performance of 78032,
15: started shipping in 1988. Used in VAXstation 3100s (except for model
16: 76), the MicroVAX 3100 models 10[e] and 20[e], the VAX 4000 model
17: 300, and the VAX 6000 model 200 and 300.
18: - Rigel - about 9 times the 78032, started shipping in 1990. Used in
19: VAXstation 3100 model 76, the VAX 6000 model 400, the VAX 400 model
20: 300, and the MicroVAX 3100 model 40.
21: - SOC (System On a Chip) -- about 6 times the 78032. Used in the
22: VAXstation 4000 model VLC and VAX 4000 model 300.
23: - Mariah - about 12 times the 78032, started shipping in 1991. Used by
24: the VAX 4000 model 60, MicroVAX 3100 model 8x, and the VAX 6000
25: model 500
26: - NVAX - depending on the system, performance ranged from 16 times the
27: 78032 to nearly 50 times. The last of VAX microprocessors and was in
28: the fastest of all VAX systems, the VAX 7000 model 800. It was used
29: in the VAX 6000 model 600, all VAX 7000 and VAX 10000 systems, all
30: VAX 4000 systems except for the (already mentioned) models 200 and
31: 300, MicroVAX 3100 model 9x, and VAXstation 4000 models 90, 90A, and 96.

43: # VAX-11/780 Systems<a name="star"></a>
44:
45: CPU-specific support for the VAX-11/780 family of systems originates

47:
48: ## Supported Hardware
49:

54: - VAX-11/782 (Dual CPU version)
55: - VAX-11/784 (Quad CPU version, very unusual)
56: - VAX-11/785
57: - VAX-11/787 (Dual CPU version)
