Resources - updates + extras
Within days of it being reported to Photodesk, here is the upgrade required to make Orrery function under RISC OS 4: Update.
I wrote these updates because I felt that Orrery's descriptions were somewhat dated, and inconsistent. Fully updated, here they are: Orrery Updates.
I have devised a selection of Setup files for Orrery. These are of general interest, but will be useful for schools: Setup Files.
Here's a special one for the Venus Transit of 8th June 2004! File compressed with !Squash.
I have manipulated recent Hubble Space Telescope images of Uranus and Pluto for inclusion in Orrery. Much better than an artist's impression... I have also included updates to the description files for the two planets: Graphics Files.
A complete set of professionally-written teaching notes for GCSE and pre-GCSE use, in Impression Publisher format : Orrery Lessons
(To download a free copy, see Computer Concepts' website)
Each of the planets has a symbol to represent them. Hand-drawn, I have made the files available in various formats. Click on the image for a 10K GIF.
