This page is dedicated to software that will run on the earliest Macintosh computers, the 128k and 512k. All the software below has been tested on a Mac 512k with 400k floppy drive, running System 2.0 and Finder 4.1.
I've provided these disk images in two formats: .dsk and .sea.hqx. The .dsk files can be used in Mini vMac or in the Floppy Emu disk emulator. The .sea.hqx files are for downloading straight to a retro Macintosh. You'll need BixHex at a minimum on older systems to unpack the hqx archive. Then the disk images can be extracted by running the .sea (self extracting archives).
While there are dozens of applications for the original Macintosh on the web, I've been selective with the software below. I've selected software that showcases these machines and still holds some interest value to today's user. Let's face it, text adventures were good once upon a time, but I can't imagine sitting down and playing one today!
The famous top view role playing adventure scroller which coined the phrase "Roguelikes".
Sierra Boxing (1985)
Arcade style boxing game. Note: this game did not fit on a 400k disk with the system folder, so this disk image is not bootable.
Mac Speak speech synthesizer (1984)
Speech emulator. This was the one used in the famous Macintosh (128k) launch video by Steve Jobs. The Mac used in the video by Jobs had 512k of ram, four times more than a retail Mac!
Packit v1, v3 (1985)
Packit archive utility, very small application, multiple files support, preserves resource fork of files.
