The Apple?
Oh
yes,
the Apple nostalgia...
The Macintosh
Still shipping today
Hey, it turns out a couple of these are still shipping! The Voxblast application is still around and I am still working on Brainvox on the Macintosh. See the neurology pages for more on Brainvox.
MacBZone
Probably my most popular game and the reason I stopped developing on the Mac. If you have an older Mac (something that can run a 68k binary), give it a try. Use the serial number 5000 and the access code 48406914. Download here. Since this app does not run on a current Macintosh (the "Classic" environment will not support and FPU), I suggest you run it under Basilisk II. With it, I grabbed this screenshot:

Others
I must have written a half dozen other Mac games/apps, but I really don't have many of them lying around anymore. As I track some of them down, I will add them here. Some titles I can remember: "The Armadillo, Nature's Little Tank", "Thursday Nights" (bowling), "Biomedical Engineering, Word of Doom", "Sokoban" (for SoftDisk Mac) and a Mac version of "Death is a Four Letter Word".
The Apple //
AppleWin (1.11.0), Apple ][ and Apple //e Emulator for Windows.

Here are a number of the more popular Apple II games I wrote over the years. Rapid fire and all with files that will run in the emulator. In roughly reverse chronological order:
Death is a Four Letter Word
I was working on this with SoftDisk when the pretty much pulled the plug on the Apple II. Top-down adventure style app with destructible terrain and an effectively infinite world size. All graphics, text, etc are in the scenarios, so every scenario had its own look and feel. The Scenario Editor is included. Download
Deflection
Simple two player "chess" like game where you move mirrors, beam splitters, etc and fire a laser to try to destroy the other player's pieces. Download
Window Pack
Simple text windowing system that won a programming contest in some magazine. It was eventually used as the interface for PBH Pack. This one requires a 65C02, thus, an Apple //e or later. Download
Digisim
A gate-level digital logic simulator. I we designing some hardware at the time and needed a tool to simulate it. The program turned out more useful than the hardware... Download
Painter
A ridiculous little game, where you enclose the bad guys like Qix and then start a limited flood fill that can be used to kill them. I was really just experimenting with an odd flood fill algorithm and turned it into a game. You have to run the emulator in Apple ][ mode for this one. Download
Pakman/Formula Nibble
These games came from Nibble magazine as I recall and I wanted more. Starting from their code, I added more levels and various other enhancements. Download Download

Totally
Shoot, shoot and shoot. Stay away from things and survive. Download
The Biomed Disk
Instead of lectures, I got to write some training material. Pretty dry stuff, but a couple of the animation techniques were kinda cool at the time. Download
Rage 3+ (and others)
Early experiments with the combination of compiled Basic and assembler. Rage is a little like Space Invaders, but plays entirely differently. Download
There were a lot more apps/games, but I'm sure I've bored you enough for one page.
