The VAX 8800 is a dual-CPU version of the VAX 8700.

(The designation 'VAX 8800' is occasionally used for the whole first generation of VAX 8800 computers - correctly called VAX 8800 Family - as well, leading to confusion sometimes.)

It belongs to the first generation of VAX 8800 computers, which includes four more models:

When the second generation of VAX 88xx computers came out in 1987, the VAX 8800 was renamed to VAX 8820N (N for Nautilus)
