NEXT MEETING                

DATE:   Monday 15th June 2026
(ROUGOL meets on the third Monday of each month)
SUBJECT:   Replay replayed
PRESENTER:   Phil Pemberton
TIME:   7:45pm (although ROUGOL members start arriving at the pub from 6.30pm and the Zoom meeting will open at 7.30pm)
VENUE:   Upstairs in the Petworth Room at The Duke of Sussex public house, 23 Baylis Road, SE1 7AY, and also online via Zoom.

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!)


The usual arrangements

Meetings are free and everyone is welcome, no booking required, just turn up at the pub. Zoom attendees contact us for the link. (If you have attended any of our previous Zoom meetings, it is the same link)

The Duke of Sussex is easily accessible by public transport from in and around London and the south east, and serves a wide range of food and drinks. All meetings benefit from a large screen display, so everyone should have a great view.

To be informed about future meetings, please join the mailing list. Everyone on the mailing list will be kept informed of these and other ROUGOL initiatives.
