The VAX-11/730 was the third VAX introduced, and the slowest implementation of the VAX architecture to have been made. By way of extensive microcoding of the large architecture, the CPU was shrunk to three hex boards. The machine seems to have been most popular for application development projects for the VAX - where the architecture was needed, but not necessarily performance.
It was also sold as VAX-11/725, which was a smaller-size packaging of the same machine.
