Playing Zork on the Arduino

If you’re looking for something to do on a boring Sunday afternoon, how about dusting off your Arduino and playing a text adventure? [Louis] wrote in to tell us about his project called AZIP, an app that will let you play classic 1980s text adventures on your Arduino.

The famous Infocom text adventure games such as Zork and Hitchhiker’s Guide to the Galaxy (reputed to be better than the book, by the way) all ran on a virtual machine called a ZMachine. We’ve seen a few unsuccessful attempts to run a ZMachine on an Arduino, but these builds usually end up going with a Linux-based single board computer. As far as we’re aware, [Louis]‘ build is the first time classic text adventures have been available on the Arduino.

[Louis] based his build on the popular Jzip ZMachine. The required hardware is fairly minimal – just an Arduino with an SD card. Right now the limitations of Flash and RAM on the Arduino means [Louis] needed to remove the game save and restore functions, but with a little clever coding and continued development those functions can be restored. Very cool indeed.

Easy to build Z80 single board computer

[Alexis] sent in a single board computer he’s been working on. The project goal of his build was making it easily reproducible. From looking at the schematics, it’s one of the simplest fully-functional computers we’ve seen. The build runs CP/M 2.2 off of two 3.5 inch floppies. This opens up a lot of options as to what software is already available. Although it operates over a serial terminal, [Alexis] pretty much duplicated an Osborne I, only at double the speed.

[Alexis] got a little e-fame from his earlier 8088 homebrew computer built from very early 8088′s rescued from an electronics junk shop. These 8088 computers made the blog rounds by playing Still Alive with a SID chip from a Commodore 64 and a YM2151 FM synth chip.

For now, I guess we’ll have to settle for a video of [Alexis]‘ Z80 computer running CP/M. Check out a video after the break of his computer running the greatest Infocom adventure, Hitchhiker’s Guide to the Galaxy.
