Features

• 6502 Hardware Programming - Provides a high-level language environment to write and execute programs on 6502 microprocessor hardware.
• Conditional Compilation Directives - Uses preprocessor directives to include or exclude code blocks based on the target hardware platform configuration.
• Hardware Porting - Adapts a single codebase to run on various 6502-based computer systems through conditional compilation and macros.
• Dynamic Memory Allocation - Allocates storage for variables and performs garbage collection on strings to maintain efficient memory utilization.
• Embedded Memory Management - Handles dynamic memory allocation and garbage collection for strings and variables within low-resource embedded environments.
• BASIC Language Implementations - Implements a functional BASIC interpreter supporting mathematical functions and floating-point arithmetic on 8-bit systems.
• Bytecode Interpreters - Implements a bytecode interpreter to reduce memory footprint and increase execution speed on 8-bit hardware.
• Single Codebase Targets - Maintains a single codebase that can be adapted for different 6502-based computer systems through conditional compilation.
• BASIC Runtimes - Runs programs written in an English-like BASIC language, including support for floating-point math on 8-bit microprocessors.
• Floating Point Emulators - Implements complex mathematical operations and decimal arithmetic via software routines for processors lacking native FPU hardware.
• Retrocomputing - Provides a development environment for building and running legacy-style software on early home computers and 8-bit hardware.
• Hardware I/O Abstractions - Abstracts character input and output through interchangeable subroutines tailored to specific hardware communication ports.
• Dynamic Memory Allocation - Implements mechanisms for allocating and reallocating memory dynamically and performing real-time garbage collection in constrained systems.
• Pure Computation I/O Abstractions - Provides abstraction layers that separate the BASIC interpreter's computation from hardware-specific character I/O routines.
• Macro-Based Generation - Generates hardware-specific machine code by expanding high-level macros into optimized assembly instructions.
• Mark-and-Sweep Garbage Collectors - Reclaims memory by identifying unreachable string objects and consolidating fragmented free space using a mark-and-sweep algorithm.
• Low-Level Machine Code Optimizations - Produces efficient assembly code tailored for specific hardware platforms using a macro system and conditional compilation.
