[ih] Hello, Internet History group

[Barbara Denny]

 I also think PPP much came later.  I was kinda wondering why you chose PPP instead of SLIP given the time frame you mentioned. I was guessing it was expediency, instead of perhaps historical accuracy for the link layer,  but maybe I am wrong. I was doing stuff with SLIP, and not PPP,  in the lab in the 80s but I was using Sun workstations.

 FWIW, those Macs did have TCP/IP - using SLIP. I think PPP came much later. But I do recall using it with Fetch (1989)
Lots of us also used terminal emulators too, including Kermit - which a friend of mine was porting to the Lisa in summer 1984. That didn’t extend IP into the Mac, though, but could be used to put about 16 different terminal windows on a single Mac (helpful for remote job management on a bunch of Sun workstations that were 1 mile and 10” of snow away at Cornell).

By-the-way, the folks from Intercon, who did a commercial TCP/IP product for the Mac back in the 1980s, are still around even if the company is not.

I think Craig Watkins would know more - I suspect he is still at crw at transcend.com

  You might also want to reach out to Jim Mathis.  I think he implemented the first TCP/IP for Apple.  I don't think he is on this mailing list. I am not sure if I still have his current email address but let me know if you can't find a way to reach him.

    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.
