Using ZRUN to run Infocom Zork games in ELF OS
A ZRUN3 Infocom game interpreter for version 3 adventures (Zork I, II, and III) is available on Mike Riley's ELF Emulation website at this link under the heading Programs for Elf/OS: http://www.elf-emulation.com/software.html.
The following are the steps involved in getting up and running with Infocom adventure games inside ELF/OS.
1) Following the link above, download the ZRUN3 Inforcom game interpreter for version 3 adventures (Zork I, II, and III) from the ELF Emulation website and use xr or xrb to send the file to your ELF/OS installation. I suggest you import the zrun3 interpreter into yor /BIN diectory so that it can be used from anywhere within your ELF/OS installation. In this example the command with xrb would be: xrb zrun3 then use the terminal xmodem to send the file to ELF/OS the way you would send any binary file.
2) If you are using ELF/OS 0.3.2 or better, you'll need to make the zrun3 binary executable with: chmod +x zrun3
3) Zork games are free to download here: http://www.infocom-if.org/downloads/downloads.html. download the zipped archives (not the Mac versions).
4) Inside the zip archives are several files. The ones we are interested in are inside the data folder named: ZORK1.DAT (in the zork1 archive), ZORK2.DAT (in the zork2 archive) and ZORK3.DAT (in the zork3 archive). Extract the ones you are interested in and use xrb to send them to ELF/OS. In this example, using xrb the form would be: xrb zork.1, then use the terminal xmodem to send the ZORK1.DAT to ELF/OS the way you would send any binary file. Do the same with xrb zork.2 and xrb zork.3 if you want the others.
That's all that's needed to get going on your new adventure. In order to start playing run: zrun3 zork.1
If you want to speed up the game, install and use the file accelerator called turbo. Run: turbo -k prior to running zrun3.
There are numerous repo's on the Internet with Infocom games. One of the most complete catalogues can be found here: The Obsessively Complete Infocom Catalog
Since it's almost impossible to finish some of the Infocom games without knowing what was included in the original box, the Infocom Gallery is a great help: Infocom Gallery
