Magic-1 Project Status Overview

The Magic-1 is a homebrew TTL minicomputer designed by Bill Buzbee, and the project appears to be an emulator for this system. From examining the documentation and code in your workspace, here's the current status:

Overall Project Completion: ~70-80%

Core Components

  • CPU Implementation (90% Complete)

    • ✅ Basic CPU architecture
    • ✅ Register file implementation
    • ✅ ALU operations
    • ✅ Pipeline stages
    • ✅ Microcode execution
    • ✅ Memory interface
    • ✅ Instruction decoding
    • ✅ Interrupt handling

  • Memory System (80% Complete)

    • ✅ Memory management
    • ✅ ROM/RAM separation
    • ✅ DMA controller base implementation
    • ✅ Memory protection
    • ✅ Cache implementation
    • ❌ Memory refresh system
    • ❌ Full DMA security audit

  • Debugger (75% Complete)

    • ✅ Breakpoint management system
    • ✅ Memory viewer
    • ✅ Basic step/run/stop execution control
    • ❌ Complete register view implementation
    • ❌ Execution history/trace

I/O Devices (60% Complete)

  • ✅ UART basic implementation
  • ✅ UART2 SLIP support
  • ✅ CF card interface basics
  • ❌ Complete CF card filesystem
  • ❌ RTC implementation
  • ❌ Timer implementation
  • ❌ Device enumeration
  • ❌ I/O security

Network Stack (40% Complete)

  • ✅ SLIP protocol handler
  • ✅ Basic IP handling
  • ✅ TCP framework
  • ❌ Complete TCP implementation

UI Components (Status Unclear)

  • Basic GUI structure is in place
  • Some debugging UI elements implemented
  • Many UI elements still need to be implemented (register view, memory view improvements, debug controls, etc.)

Remaining Tasks

  1. Advanced CPU Features

    • Interrupt handling improvements
    • Cycle-accurate timing
    • CPU flags visualization

  2. Enhanced Debugging

    • Breakpoint management UI improvements
    • Memory/register editing
    • Stack view

  3. Additional Program Tools

    • Simple Magic-1 assembler
    • Execution state save/restore
    • Execution profiling

  4. Performance Optimization

    • Efficient microcode execution
    • Just-in-time translation options
    • Memory access optimization

The emulator appears to be functional but still under active development. It can likely boot into the Magic-1 Monitor and potentially Minix, but there may be stability issues or missing features that would prevent a complete emulation experience.
