There are four single VAX 88x0 computer models, depending on the number of CPUs installed in the basic cabinet:
- VAX 8810 - 1 CPU
- VAX 8820 - 2 CPUs
- VAX 8830 - 3 CPUs
- VAX 8840 - 4 CPUs
The first three may be upgraded in the field by the installation of additional CPU(s).
Additionally there is a prepackaged VAXcluster system VAX 8842 made of two VAX 8820.
