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

Anti-Goals

Design

TCP

UDP
