Sage Computer Technology

[3] Hardware: The SAGE managed multitasking with six serial ports in real time with 1 MByte of RAM in 1983.

Graphics capability was possible with the addition of a third-party colour graphics system from Robinson Systems which plugged directly into the Sage 68000 bus and provided output compatible with a range of colour monitors (e.g., Cotron Sword, Electrohome 1301).

Many other operating systems were available[8] including CP/M-68K, Idris, PDOS, HyperFORTH Plus, BOS, TRIPOS, Mirage, and MOSYS.

Programming languages available included Pascal, Modula-2, C, FORTRAN77, BASIC, 68000 macro assembler, APL, BCPL, LISP and Forth.

It works by putting a special reflective pencil behind your ear and a quadrature detector that tracks its movement.
