Cave (and later Cave-Plus) were MUDs for the BBC Micro, initially released back in 1985.
This repository contains original dumps of the source code (from a few different places). I make no claims whatsoever regarding the copyright.
The original BBC BASIC files have been detokenised, thanks to BBCBasicToText.py which is in the scripts directory. Please note that this needs Python2 to work correctly.
You don't need the original hardware (including Econet!) to enjoy Cave. I put together a remodelling using the Ranvier MUD system: https://github.com/tgreaves/ranviermud-cave
When the first player enters the Cave, OBJINIT is loaded which sets object locations.
In Cave-Plus, certain magic items items (Shield, Crystal, Staff, Amulet and Treasure) are then placed in random locations, but not areas 16-20 (Wizard's Room and surrounding areas).

Note that in both versions, mobs are placed in pre-determined initial locations as defined in the DATA file.
