The GlobalTalk Network

In March 2024, a rabble of retrocomputing enthusiasts on Mastodon put together a network for old Macs across the internet. Self-organised via Google Sheets, they joined together their various local networks using the long-obsolete Apple Internet Router 3.0 software installed on both real vintage Macs and emulators. Somehow, it all worked! The network was dubbed GlobalTalk - a reference to the legacy AppleTalk suite of networking protocols being used. By mid-March, GlobalTalk had already connected roughly 50 separate networks across the globe. This talk will include: • An overview of old Macs and how their networking protocols evolved from the early days through to today • Some details about how AppleTalk, Apple Internet Router 3.0, and the modern internet still interoperate • A bit of software and network protocol "archaeology" • A live demonstration of connecting to the network, and some of the cool things GlobalTalk participants did with the network, such as the HyperCard-based "AppleWideWeb"
