# 68040pc

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.

## Status

The `testboard` design is almost complete. I'm going to sleep on the design

before ordering boards. The FPGA does address decoding and interrupt

management and will contain a sound core to output some cool beeps through

the I2S DAC module. I'm pleased with how the project is going so far!

## Objectives

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.

## Performance Expectations

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.

## Learning and Documentation

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.
