Why the Apple II Didn't Support Lowercase Letters (2020)

> So my TV Terminal, for accessing the ARPAnet, was uppercase only.

I never realized that the most influential personal computer was specifically designed to access what would later become the internet. That's astounding.

(The first internetworking experiments that I can find records of were done as part of the ARPANet project, and some of the protocols and even many of the port numbers we use today in TCP/IP are from ARPANet.)

I also had no idea that Woz had built his own CPU out of discrete logic in 01970. I still haven't done that myself 55 years later!

I believe the internet is a direct continuation of ARPANet. It just got renamed at some point.

The ARPAnet (the electronic system) was never an internet (or catenet). It predated internetworking, and it was one of the networks comprising the internet we are using now (specifically, it was 10.0.0.0/8) until its demise in 01990. As a social institution, though, you are correct: the internet we are using now started out as an experiment inside the ARPAnet project.
