Before I joined the computer security industry in the early 1990s, I used to write computer games for the Sinclair ZX81, Memotech MTX512, Prime Minicomputer, and IBM PC. Here you can find out about some of them:
Humbug – a better DOS text adventure game. (Either play it online, or download). Check out reviews here, including the definitive in-depth review by Joe Pranevich on The Adventure Gamer blog.
Blox – a shameless Tetris rip-off with a nice Boss key.
In 1992, Red Herring magazine interviewed me, and published a couple of articles about my games. If you’re curious you can check them out below (click for larger versions).
And here’s a nice review Sue Medley wrote about Jacaranda Jim for Zero magazine.
