Obsolete Procedure Call

July 16, 2018 · View on GitHub

Obsolete Procedure Call (OPC) is a protocol intended for performing remote access to a machine that is controlled (or simulates being controlled) by a Z80 processor. It can be useful for testing hardware without having to physically use the target computer (using a modern machine with modern tools instead), or to test Z80 code agains a real Z80-based system.

Protocol specification
Server written in C - includes an implementation for MSX computers.
Client library for .NET - includes a sample application that remotely retrieves some information from a MSX computer.
