PASTA/80: Turbo Pascal 3.0-Compatible Compiler for Z80 Systems
By

A five-star bake. Worth schmearing, sharing, saving.
Summary
PASTA/80 is a Pascal cross-compiler that targets Z80 microprocessors, generating machine code for classic systems like ZX Spectrum 48K/128K/Next and CP/M. The compiler follows Niklaus Wirth's single-pass recursive-descent approach, generating code during parsing without an explicit syntax tree. While it prioritizes compilation speed over optimization efficiency and doesn't compete with modern compilers like LLVM, it maintains Turbo Pascal 3.0 compatibility for retro computing enthusiasts.
