An other way is actually to use a modern "interpreter" for these games.
Infocom created a virtual machine, the "
Z-machine" to simplify the porting to the various range of 80's computers. The game file itself is the same on every machines, only a small executable (the "interpreter") is different for each machine.
Today, you can use software like
WinFrotz or
Gargoyle to run these games on modern computers, laptops, tablets, phones...
It's still possible today to create this kind of interactive-fiction games, (and compatible with the software above). Take a look at
Inform 7 for example.
I am a writer since some years, all my games are playable online or offline, even on old computers. Unfortunately, it seems that no zmachine interpreters were made for the Dragon...
