This machine featured a 3-stage pipeline and proprietary 32-bit bit- slice processor. It offered VAX 11/780 performance "at about one- quarter the cost." It was used in simulation, VLSI design, and AI environments and was marketed as a "supermini in a box". It ran UNIX, FORTRAN, Pascal, and C, and had a bit-mapped color display (1024 x 1024), 16K cache, and 256MB virtual memory. The Apollo supported "transparent virtual memory access," a form of clustering in which adding more Apollo machines to a network improved performance.
