February 14, 2019 – TRS-80 Network Interface Card

Peter Cetinski has been working on a project that provides a simple, cheap, WiFi based, encrypted Internet communications via the TRS-80 by connecting to the Model III and Model 4 expansion port.

TRSNIC provides the foundational protocols required to implement modern network interactions on the TRS-80 microcomputer. The first such protocol provided is TCP/IP via an implementation of the Berekely Sockets API. TCP/IP is the dominant low level network protocol in use today. Many of today’s higher level network protocols like HTTP and FTP are implemented on top of TCP/IP. This means many modern networking applications and systems can be built upon the base TCP/IP support provided by trsnic.
