      A port of CamelForth for the RCA 1802 is now available. Get it at
      Brad Rodriguez's site http://www.camelforth.com

      It runs on a PC-hosted 1802 instruction set simulator that is also
      included in the download. The simulator emulates the Forth words
      ACCEPT and EMIT using standard Input/Output, and provides Forth-level
      and instruction-level tracing options.

      It's a Direct Threaded implementation. The code field for high-level
      words is just a one-byte SEP instruction. Colon, User, Variable, and
      Constant words each have their own program counter, as does Next.

      The only exception is a CREATE'd (formerly known as <BUILDS) word
      that may have its code field updated by DOES>. For this case, the
      code field is three bytes - a SEP plus an address.

      CamelForth for the 1802 passes all the applicable tests in John Hayes
      and Gerry Jackson's ANSI Forth conformance test suite.
