HP-41CX Emulator Tools #

Dive into the nostalgic brilliance of the HP-41CX with hp41cx_tools, a dynamic work-in-progress suite crafted for retro computing enthusiasts! These command-line tools empower you to decode and convert memory dumps and FOCAL source code for PX-41CX and DM41X emulators. Written in Ada 2022 with AdaCL for robust reliability and paired with Make for seamless test execution, this toolkit runs flawlessly on macOS, Linux, and Windows — no Excel or web dependencies required!

Why Choose hp41cx_tools? #

  • Cross-Platform Power: Unlike Windows-only alternatives, these tools shine on macOS, Linux, and Windows.
  • Scriptable Simplicity: Command-line design integrates effortlessly into automated workflows.
  • Open Source: Hack and extend the code on SourceForge.
  • Comprehensive Docs: Explore detailed guides via GNATdoc.
  • Rigorous Testing: Comprehensive AUnit test suite, launched via make test, ensures reliability with edge-case coverage.
  • Lightweight: No need for Excel or web-based compilers, just pure retro computing magic.

Compared to Others: While feature-rich tools like PX41CX_Interface.xls, DM41 programming tool, or HP41UC offer more input and output formats including even generating bar codes, hp41cx_tools focuses on command line use and portability.
