Hello everyone,

I just joined the Internet history group today. A brief introduction: 
Since April 2020 I have been working on implementing the Internet 
protocols on the earliest models of Apple Macintosh: the Mac 128K and 
Mac 512K from 1984. The goal is to implement the original triad of 
Internetworking applications: electronic mail, FTP, and Telnet on the 
first models of Macintosh. I am using PPP over the serial port as the 
link layer.

I enjoy programming in 68000 assembly language, and I also know 6502 for 
the Apple II. I first started programming Apple computers around 1999, 
and vintage computing is today one of my hobbies.

While implementing TCP on the early Macintosh, I have a few questions 
which are mostly on the philosophy of design, evolution, and rationale 
behind some features or design decisions in TCP/IP, and I'll dole these 
out in the coming days or weeks.
