Clean Up

Earlier this year, I lost the directory where I kept my downloadable diskette images.  These images were ones I created for this blog. I had no direct backup for this directory so I spent some time going over my computers,

Retrochallange 2015/01 Third Post

I worked on my challenge for a short time while watching a movie, The Prince of Persia.  I thought it was fitting to be working on an Apple II game while watching a movie inspired by iconic Apple II game. It’s funny,

Retrochallenge 2015/01 Second Post

In order to play Eamon you need at least one diskette from the Eamon Library.  The Main Hall and Beginners Cave (EAMON001.DSK) is where everything starts, and hopefully ends. In order to create more adventures a second diskette, the Dungeon

Power Supplies
