Amongst the RISC OS source code that has been "released" over the years is Acorn's original ground breaking video system, Replay. Phil Pemberton has taken on the brave challenge of getting it running again and trying to understand Sophie's highly optimised ARM code!

As well as the playback frontend and decompressors, he has also been
looking at the compressors and using them to create the first new ARMovie files in many years. Phil will give us a brief run through what he has
found and demonstrate the different compression techniques and some of the movies produced.

(If there is time/interest, Phil can also talk about how to use
Transputers to turbo charge your Archimedes!)


Directions to the venue by car (there is parking directly outside the pub
on Coral Street) and public transport (recommended!) are on the website:
