Purpose
This tool is a Gopher protocol browser designed specifically for classic Macintosh 68k systems (System 6 and 7). It supports multi-window browsing, file downloads, and various display themes.

Security Assessment
The overall risk is Low. The automated code scan checked 3 files and found no dangerous patterns, malicious code, or hardcoded secrets. It does not request any dangerous permissions. As a network client, it inherently makes outbound connections to fetch data from Gopher servers, but it does not access unauthorized local sensitive data or execute unexpected shell commands.

Quality Assessment
The project is clearly documented and uses the permissive ISC license. It is highly active, with its most recent code push occurring today. However, it has very low community visibility, currently sitting at only 6 GitHub stars. It is also worth noting that the entire codebase was generated agentially using Claude Code, meaning human review of the generated C code is highly recommended if you plan to modify, integrate, or deeply trust the software.

Verdict
Safe to use.
SUMMARY

A Gopher browser for classic Macintosh 68k systems

README.md

Geomys

Geomys is a Gopher browser for classic 68000 Macintosh computers. It supports monochrome and 256 colors, System 6 and 7, multi-window browsing, themes, favorites, Gopher+ protocol, file downloads, and keyboard navigation.

This project was 100% built agentically using Claude Code.

Themes

Geomys ships with 14 built-in themes selectable from Options > Theme. Each window can have its own theme - changing the theme applies only to the active window, and new windows inherit the active window's theme.

Theme Type Description
Light Mono White on black, default. Works on all systems.
Dark Mono Black on white. Works on all systems.
Solarized Light / Dark Color Ethan Schoonover's Solarized palette.
TokyoNight Day / TokyoNight Color Based on the Tokyo Night color scheme.
Amber CRT Color Amber phosphor CRT aesthetic.
System 7 Color Macintosh System 7 with CLUT accent colors.
Dracula Color Dark purple-accented palette.
Nord Color Arctic blue-tinted palette.
Green Screen Color Phosphor green on black CRT aesthetic.
Classic Color 1990s web browser colors.
Monokai Color Dark warm palette with vivid accents.
Gruvbox Color Retro earthy palette with warm accents.

Building

Requires the Retro68 cross-compilation toolchain. Build it from source (68k only):

git clone https://github.com/autc04/Retro68.git
cd Retro68 && git submodule update --init && cd ..
mkdir Retro68-build && cd Retro68-build
bash ../Retro68/build-toolchain.bash --no-ppc --no-carbon --prefix=$(pwd)/toolchain

Then build Geomys:

./scripts/build.sh

Build Presets

Geomys supports fully customizable builds. Three presets cover common configurations:

Preset Windows Features Memory
full 3 all features ~2560KB
lite 2 core browsing ~1024KB
minimal 1 only essentials ~512KB

The default build uses the full preset. Select a preset with --preset:

./scripts/build.sh --preset minimal    # stripped, for 1MB Macs
./scripts/build.sh --preset full       # everything, 3 windows

Individual features can be toggled with --feature / --no-feature flags. Presets are applied first, then individual flags override:

./scripts/build.sh --preset lite --gopher-plus --styles
./scripts/build.sh --max-windows 2 --color --no-cache

See docs/BUILD.md for the complete list of build flags, feature details, memory costs, and examples.

Memory and Multi-Window

On System 7 with MultiFinder, Geomys requests a memory partition via the SIZE resource. Default allocations:

Preset Preferred Minimum
Full 2560KB 1536KB
Lite 1024KB 768KB
Minimal 512KB 256KB

Large Gopher directories (1000+ items) use significant memory (~300KB per directory). With multiple windows open, the second and third windows may show fewer items if heap space runs low. This is normal on a 4MB Mac.

To increase memory on machines with more RAM: select the Geomys application in Finder, choose File > Get Info, and increase the "Application Memory Size" field. No rebuild required.

Testing

  • System 6 (monochrome): Snow emulator (v1.3.1) with Mac Plus ROM and System 6.0.8 SCSI hard drive image. DaynaPORT SCSI/Link Ethernet emulation for MacTCP networking.
  • System 7 (color): Basilisk II emulator with Macintosh IIci ROM and System 7.6.1. Color QuickDraw support for 256-color themes and multi-window testing.
