(There's no video for MacASM 1.2 yet. Please contribute to MR and add a video now!)
MacASM was the first assembler for Mac. It only supports System 1 to 6 (not System 7 and up). Useful for making apps that will run on 1984 to 1986 Macintosh models. Starting from System 6 in the late 80's, THINK Pascal was a much better choice for programming on the Mac.
