SYSMON65 - Custom Proteus VSM Models

Overview

Welcome to the master repository for my SYSMON65 Single Board Computer simulation components.

This repository contains a collection of custom-built Virtual System Modelling (VSM) components for the Proteus Design Suite. Because standard Proteus lacks complex models for certain retro hardware, I developed some of these C++ DLLs from scratch to accurately simulate the peripherals, video pipelines, and interfaces required for a complete 65C02-based architecture.

Repository Structure

Each folder in this repository contains the C++ source code, compiled .dll models, and testing environments for a specific hardware component:

Directory	Description
6522 Proteus Model	MOS 6522 VIA: My Custom C++ model of the Versatile Interface Adapter. Handles parallel I/O and hardware timers essential for the 6502 ecosystem.
6502 Proteus Model	CPU & Architecture Support: Contains files, memory decoding logic, and simulation support structures for the core 6502 processor architecture.
9938 VDP Proteus Model	Yamaha V9938 VDP: Custom model of the MSX2 Video Display Processor. Handles dedicated VRAM, hardware graphics rendering, and outputs discrete video timing signals.
Protues LIB	Schematic Symbols: Contains the Proteus .LIB files. These are the visual schematic symbols and pin definitions that link to the compiled C++ DLLs. (Note: Matches Proteus directory structure).
RGB Screen	RGBOUT Monitor Simulator: My custom VSM display module that acts as a physical CRT. It reads raw PCLK, HSYNC, VSYNC, and 3-bit Digital RGB signals from the VDP and paints them to a Windows UI popup with 2x2 integer scaling.
i8255 Proteus Model	Intel 8255 PPI: Custom C++ model of the Programmable Peripheral Interface, providing additional parallel I/O expansion capabilities.

⚙️ Global Installation Instructions

To use these components in your own Proteus workspace, you need to copy the compiled models and libraries into your local Proteus installation directories:

1. Download or clone this repository.
2. Navigate to your local Proteus installation (typically C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\).
3. Copy the .LIB files from the Protues LIB folder into your Proteus LIBRARY folder.
4. Copy the compiled .dll and .bin files from the individual model folders into your Proteus MODELS folder.
5. Restart Proteus. The new components will now be fully indexed and available in your Component Picker (P).
