WIP: This week for my @circuitpython.org game running on the @adafruit.com #FruitJam, I worked on some physics, created a ship graphic, added text to the display and updated the screen graphics. I think it is coming along nicely.

WIP: New project. Starting simple, I'm working on the mechanics/physics of a re-imagined #retro game from the past. @circuitpython.org @adafruit.com #FruitJam

Fun fact: text stored in a story file for a #ZMachine game (i.e. #Zork) is encoded as 5 bits, so 3 characters could be stored in 2 bytes(16 bits). Every byte counted back in the day. Didn't know there was a history using 5 bits for text. Thanks @anneb.bsky.social !

My college years saw big changes in computer technology. As a freshman we used punch cards for computer assignments. Later years we switched to terminals and in my senior year the Apple Macintosh 128K arrived on campus.

Using CircuitPython For Running a Z Machine? Yes!

For several years I have been thinking about how cool it would be to have a CircuitPython-based Z Machine for running Zork and similar adventure games. Unfortunately, no one had written one that I kno...

I have fixed all the known bugs to date and I have all the initial features I want so I have released the first production (i.e. non-beta) version of the CPZ Machine. #Zork #ZMachine @circuitpython.org @adafruit.com #FruitJam

FYI if you are looking for a maze algorithm, I wrote a learn guide about one here:

Working for a value added reseller at the time, we sold a few of these for use with AutoCAD. We affectionately called it "the pizza box". A few years later, Sun came out with the SPARC classic, which we affectionally called it "the personal pizza box".

Finally I have a video captured screen shot of my CPZ Machine playing #Zork. The font can be changed in the program. The included fonts allow screen sizes from 64x22 (this screen shot) to 106x40 characters.

Version 1.0.1 of my CPZ Machine project was just released to fix a bug where the program would no longer listen to you after entering a blank line (how rude!).Recommended update. @circuitpython.org @adafruit.com #FruitJam #Zork #ZMachine

Did you know that the CPZ Machine has 5 retro color themes to choose from for your #ZMachine #Zork adventures? This one is called “Amiga”. @adafruit.com @circuitpython.org

Yes, version 3 games should work. I was not sure of the copyright issues so I only included one game. You can copy more games to the "stories" folder and then select the game when the program starts up.

Does your breakout game need any modifications to work with the fruit jam?
