ReadMeDocs/Hints+Tips
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

File contents
Hints & Tips ============ This file contains hints and tips for running ArcWeb. Some of these are mine, others are ones I've seen posted on the net or had emailed to me. There are so many contributors that it would take too long to list them all. Summary of Contents =================== Using RAM disc for the cache Aborting a Fetch Clickable Images (faster use of) Using RAM disc for the cache ---------------------------- Several people have noticed that if the cache is set to a directory in a suitably large RAM disc, speedups occur. I have tried this myself, but I couldn't detect much difference, although I did only try it with smallish documents and images. Obviously you lose the entire cache when you reboot. I would imagine that you need quite a generous size, at least 8MB to be safe. Aborting a fetch ---------------- You can click on the animated web icon to request that a fetch is stopped. This works all the time, whereas the Stop button only interrupts during the page rendering. Clickable images ---------------- Some images are sensitive to mouse clicks so that if you click on a particular part of the image, you visit a different page. These 'imagemaps', as they are called, are very pretty and nice to use - you can see an example at http://www.acorn.co.uk/ where the signpost is one of these 'imagemaps'. The problem with imagemaps is that when you click on a particular part of the image, the browser has to carry out TWO document retrievals in order to process that click - the first is a request to the server to ask it which document it should view, and the second will be the real request. This will cause a longer delay in retrieving the document than would be the case normally. While the WWW developer community is working to address this problem, there is a workaround for users. Using Acorn's home page as example, you will see a mini-menu underneath the image representing all the destinations which are contained in the image. Clicking on these links will omit the first step mentioned in the previous paragraph, and go directly to the page concerned.
