Isotope60.co is an experimental organization which hosts a public Gopher service focused on simplicity, structured information, and long-term accessibility.

Isotope 60 - Cobalt

Cobalt-60 is a byproduct of nuclear reactor operations. It is formed when steel rods are exposed to neutron radiation. It is essential to the medical community for cancer treatments and sterilizaiton of medical devices. Cobalt-60 contains 27 protons, 27 electrons, and 33 neutrons and is a radioactive isotope of Cobalt with a half-life of 5.2714 years.

What is Gopher?

Gopher is a pre-web Internet protocol created in 1991 that provides a simple, hierarchical, text-based way to distribute files and documents. Unlike the modern web, Gopher is intentionally lightweight, structured, and free of scripts, trackers, and advertising. Unfortunately, it is also also free of security.

It emphasizes clarity, permanence, and human-readable organization.

Accessing the Server

The server is accessible using any Gopher client. We recommend Lynx.

Host: gopher.isotope60.co
Port: 70
URL: gopher://gopher.isotope60.co

Command-line example:

lynx gopher://gopher.isotope60.co

Or:

printf "\r\n" | nc gopher.isotope60.co 70

Content

The server provides a structured archive of plain-text materials, projects, documentation, and curated public resources.

Content is intentionally presented in simple formats to remain accessible to low-bandwidth systems and long-term archival use.

Purpose

This service exists as an exploration of minimal network design, protocol literacy, and durable information systems. It is running on a Particle Tachyon single-board computer with 8 GB of RAM and a 64 GB micro-SD card for a hard drive.

Gopher predates the web and continues to function reliably with minimal overhead and maximal transparency.
