Z88dk is a SmallC+ and Z80 assemler cross compiler supplied with an assembler/linker and a set of libraries implementing the C standard library for a number of different z80 based machines. The name z88dk originates from the time when the project was founded and supported only the Cambridge z88 portable.

Supported machines: Cambridge Computers z88, Sinclair ZX Spectrum, Sinclair ZX81, CP/M based machines, Amstrad NC100, VZ200/300, Sharp MZ series, TI calculators (TI82, TI83, TI83+, TI85, TI86), ABC80, Jupiter Ace, Xircom REX 6000, Peters Sprinter, Sam Coupe, MSX1, Spectravideo, Mattel Aquarius, Peters Sprinter, and C128 (in z80 mode) machines.

Features:
* Small C+ based compiler with structs, floats and other ANSI extensions
* Module assembler/linker which only includes required library routines
* Peephole optimizer with rulesets that reduce the size of generated code
by ~30% and improve speed
* Easily retargetted C library including stdio routines
* Retargettable VT100 terminal
* Support for over a 25 z80 based machines (see below for details)
