The VAX11-780 was a one MIPS (one million instruction
per second) machine that became an industry standard: DEC dubbed its performance
one VUP for VAX Unit of Performance; but "standard" benchmarks as the SpecMark89,
SpecInt92, SpecFp92 are also based on the 780.
The processor unit depicted to the left contained the
SBI (synchronous backplane interconnect; said to be borrowed from a never-finished
36-bit machine, the "Unicorn"), CPU (KA780), FPP (FP780), memory, UNIBUS
adapters (DW780), power supply and the console, an LSI-11 (PDP-11/03)
processor. A usual configuration contained 4MB of ECC RAM. A commercial
"hit", and a very reliable machine too: a few of them are actually in use
even this day (2000), and they were "cloned"
