Welcome to the 68040pc (working name) project, an ambitious endeavor to build a general-purpose computer platform powered by the Motorola 68040 (or, in this case, the 68LC040) CPU. Inspired by creations like Ben Eater's breadboard 6502 computer and me finding a 68LC040 in a bin, this project seeks to bring the charm of vintage computing into the modern era with a twist of power and utility. Call me crazy, but I expect to be able to use this machine when it's done.

The testboard design is almost complete. Most of the logic checks out in the schematic. Need to add a 3.3V power supply and reset, interrupt, and user button circuitry.

The 68040pc aims to be versatile and user-friendly, with the following capabilities:

• Input/Output: Support for keyboard (text input) and mouse for GUI interactions.
• Display: Text display for command-line operations and a graphics display ready for GUI applications.
• Storage: Compatibility with standard bulk storage devices, including floppies and hard drives.
• OS: Capability to run a preemptive multitasking operating system.
• Expansion: A robust expansion system, ensuring the platform remains relevant and adaptable after its initial production.

With the integration of the 68040 CPU and the potential to accommodate up to 512MB of RAM, I anticipate the 68040pc will rival the performance metrics of systems like the Amiga, especially in terms of computational power. Although the base system might not match the Amiga's graphical prowess, there's potential for future enhancements via expansion cards to bring it to that level.

This journey isn't just about creating a new machine—it's a significant learning curve for me, and I want it to serve as an educational resource for others. Every step of the way, the system will be meticulously documented. From design decisions to implementation nuances, the goal is to demystify the process and make the knowledge accessible to all.
