Model T TCP Architecture

Overview

Presumably, a TCP stack on the Model 100 cannot be done. The 8085 is just too underpowered. All the more reason to do it, right?

This article is a place to hash out goals, anti-goals, and a design

Goals

• Code runs from Option ROM
• Implements IP, TCP, UDP, PPP
• Header compression
• 100% 8085 assembly language
• May provide option to assemble for Z80/8080 as well
• Implements hardware flow control signals
• 19200bps
