The DN10000 is the bit-slice implementation of the RISC chip Apollo
designed.. Here's a note from a computer architecture site:

PRISM (3-wide LIW), 1988 - Barry Flahive, Rick Bahr, and John Yates
John Yates contributed the multi-issue idea. PRISM was a 3-wide machine --
in each successive clock tick, you could do a floating-point add, a
floating-point multiply, and an integer operation (typically a LOAD, for
instance of two floating point registers). Perfectly balanced for
single-precision Linpack or FFT.

DN10000 - the first (and last) model, 54 MIPS, 36 megaflops in 1989.
Paul Mageau and Andy Milia were chiefly responsible for the memory system.
Doug Voorhies, Olin Lathrop, and Dave Kirk were chiefly responsible for the
graphics system.

Therefore, the DN10000 is the bit-slice implementation of PRISM... A bunch
of the stuff in PRISM went into PA-RISC 1.1, I believe... The date for
PA-RISC 1.0 is 1987, don't know now of any machines besides one model of
3000 that use it...
