Doctor Who and the Mines of Terror

Technical specifics

The game is one of the first (and only) games for BBC Micro that came on both a tape/disk and ROM. The player has to install the ROM in the BBC Micro's ROM Slot, and then load up the game.

Rumors

It is said that Micro Power put so much money into developing this game that it significantly contributed to them going bankrupt.

Much of the expense mentioned above went into developing a Spectrum version which was ultimately unreleased.
