Dvorak on Typing / Mac
Dvorak on Typing was a typing tutor for PC computers in DOS. It did the basic tutoring you'd expect, but it also had a mode very much like a video-game, where your success at typing helped a knight proceed through battles from screen-to-screen to defeat a dragon.
Silicon & Synapse (later Blizzard Entertainment) was contracted by Interplay Productions to conver the project from DOS to Macintosh.
Unfortunately, they didn't have the source code, only the art assets. (This was a regular occurence at Interplay -- they frequently lost the source code to old projects. Really).
Consequently, we needed to write the game from scratch, using the original as a template. I started the initial work, developing low-level hooks for Mac to be able to control keyboard input and text-rendering, which required some assembly language. Fortunately I had hacked my way around patching Mac traps before (thank you, MacTutor magazine), and so this was relatively easy.
Before I could finish the project I was called upon to work on other projects, and so handed off programming to a contractor and fellow UCLA grad Jeff Schubert, while I stayed on as project producer briefly before handing off that role to Allen Adham.
The scope of this project -- developing a project from scratch -- was a much, much larger project than any of us realized at the time, as the project was deceptively large. Jeff, who consumed around 200 liquid ounces of Coca Cola per day in (2 big gulps and a six pack), plugged away at the project until it was done. Kudos Jeff!
