I wasn't aware there was a difference, I mainly just remember the copy of the book I had all those years ago and incorrectly assumed all the content was ported from the original.
Maybe you could cheat: there are a fair few emulators of that era of machines that you can SSH into, drop the code into one of those and run as originally intended! Or access via the web by hooking shellinabox up to connect to the emulator's console. You'd need to add some layer of authentication if making this available on the public internet for friends to access though. Might be easier to setup than actually porting that old “minified” code (with single-character variable names, GOTO-a-plenty, & minimal comments) and implementing something to manage multi-user access to the same game instance.
Thanks for the heads up on the web-capable versions of the other games. That's pretty cool indeed.
I hope someone takes on the few missing multiplayer games from the DEC version at some point but figuring out how to port them is going to be a lot of work!
