Join Mark, Jon and Danny as they traverse the M section of the Hitchhiker's Guide to the Galaxy.

Matter transference beams

Ford and Arthur are teleported from the smouldering remains of the Earth to the Vogon ship, via a matter transference beam. A song that regularly used to be chanted by huge crowds outside the Sirius Cybernetics Corporation Teleport Systems factory on Happi-Werld III goes "If you have to take me apart to get me there, then I don't want to go".

Max Quordlepleen

Max Quordlepleen is the MC at Milliways, the Restaurant at the End of the Universe. He's an absolute pro, who divides his time between this upscale restaurant and the Big Bang Burgar Chef.

Megabrantis

The Megabrantis cluster is the political hub of the galaxy. The Vogons migrated away from their homeworld to setup shop here. Brantisvogan is a planet within the cluster, and you can go back to episode 8 to hear all about that.

Megadodo Publications

Megadodo Publications was once the home of the Hitchhiker’s Guide to the Galaxy, and one of the great publishing corporations of Ursa Minor. I think we can assume that Playbeing is another Megadodo rag, so presumably the company was doing fairly well.

Mella

Mella is a Golgafrincham woman Arthur meets (along with Agda) on the prehistoric Earth.

She had recently escaped a lifetime of staring every morning at a hundred nearly identical photographs of moodily lit tubes of toothpaste in the art department of a Golgafrinchan ad agency.

We never got to find out what happened between Mella and Arthur, because the book ended.

Memory dump module

A memory dump module is a small unit that Ford uses to copy data from his Guide (after wiping off the bits of fluff and biscuit crumbs). Adams clearly understood not only the need for data portability, but that people would be pretty careless with these devices. Nowadays we call them USB sticks or something similar.
