I spent some digging into and disassembling the classic Horses demo for the Apple ///. The main part of the code is implemented in an Invokable module written by Andy Hertzfeld. This is loaded in by the Basic program and it's functions called from there.
I found an interesting header in the invokable code file, looks like a remnant of the original source!

Read more here in my blog post:

And the disassembled code is on github:

This code needs to be assembled by the Apple II or /// Pascal Assembler to produce the required PCD code file.
