This collection of Infocom Z-code interpreters from the 1980s includes assembly source code for various home computers. Some interpreters also have compiled binaries. The repo also contains internal documentation on creating floppy disks for each platform. Interestingly, many directories include “assembled printout” files, which are text files containing assembler output for a complete program. The DIP interpreter used to implement Fooblitzky has a unique architecture and different opcodes compared to the Z-machine. The game files in this collection seem to include graphical sprite data within the high VM memory.
