• The Robotics Practitioner (TRP)

  This quarterly magazine ran from Winter 1995 until Spring 1996. TRP was acquired by Bill Gates in the Fall of 1996 and lives on as the Robotics Digest.

  • Enhancements to the Simple 68HC11 Robots Volume 1, Number 3, Summer 1995, pages 21 - 32.

   

• Robotics Digest (RD)

  This quarterly magazine was started in the Winter of 1997, as a follow-on to TRP, by Bill Gates and Whirlwind Publication (not the Bill Gates of MS).
