The VAX 8800 is a dual-CPU version of the VAX 8700.
It belongs to the first generation of VAX 8800 computers, which has got 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)
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.
