The MakerLisp Machine is a portable, modular computer system, designed to recapture the feel of classic computing, with modern hardware. The CPU is a Zilog eZ80 running at 50 MHz, which supports up to 16 Mb of zero wait state RAM. The system software is 'MakerLisp', a 'Lisp on Bare Metal' system that allows direct access to system hardware, while providing the concise expressive power of a functionally complete Lisp environment. The machine is also an ideal platform for an extended CP/M. A full system configuration is pictured above, with CPU, expansion board, USB keyboard, and VGA display, in the laser-cut wood 'MakerStation' enclosure.
