  Mars
   n.
  
      A legendary tragic failure, the archetypal Hacker Dream Gone Wrong. Mars
      was the code name for a family of PDP-10-compatible computers built by
      Systems Concepts (now, The SC Group): the multi-processor SC-30M, the small
      uniprocessor SC-25, and the never-built superprocessor SC-40. These
      machines were marvels of engineering design; although not much slower than
      the unique Foonly F-1, they were physically smaller and consumed less
      power than the much slower DEC KS10 or Foonly F-2, F-3, or F-4 machines.
      They were also completely compatible with the DEC KL10, and ran all KL10
      binaries (including the operating system) with no modifications at about
      2--3 times faster than a KL10.
  
      When DEC cancelled the Jupiter project in 1983 (their followup to the
      PDP-10), Systems Concepts should have made a bundle selling their machine
      into shops with a lot of software investment in PDP-10s, and in fact their
      spring 1984 announcement generated a great deal of excitement in the PDP-10
      world. TOPS-10 was running on the Mars by the summer of 1984, and TOPS-20
      by early fall. Unfortunately, the hackers running Systems Concepts were
      much better at designing machines than at mass producing or selling them;
      the company allowed itself to be sidetracked by a bout of perfectionism
      into continually improving the design, and lost credibility as delivery
      dates continued to slip. They also overpriced the product ridiculously;
      they believed they were competing with the KL10 and VAX 8600 and failed
      to reckon with the likes of Sun Microsystems and other hungry startups
      building workstations with power comparable to the KL10 at a fraction of
      the price. By the time SC shipped the first SC-30M to Stanford in late
      1985, most customers had already made the traumatic decision to abandon the
      PDP-10, usually for VMS or Unix boxes. Most of the Mars computers built
      ended up being purchased by CompuServe.
  
      This tale and the related saga of Foonly hold a lesson for hackers: if
      you want to play in the Real World, you need to learn Real World moves.
