DrupalZM – West of House

I’m pretty excited about DrupalZM, things are going fairly smoothly. I fixed up a few major bugs with signed number calculations and the z-character -> zscii -> ascii converter. I also implemented more opcodes, as well as the output buffer that takes care of rendering text to the screen properly and in a controlled fashion. The machine now executes until it expects user input! Definitely exciting, as this means that the object table is being correctly manipulated and read (e.g. the west of house object, the cretin (the player), the mailbox, etc). Below is text from DrupalZM – the expected text for the starting room of Zork I!
