PCA/Docs/Licence
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.

Plug In Compliant Application protocol ====================================== Licence conditions ================== You are invited to add the PCA standard to your programs and to create PCA 'applets'. However, before publishing or distributing (in any form) a program which makes use of the PCA standard you must first obtain a licence to do so from Clares Micro Supplies. The licence is currently free of charge and early adopters will be guaranteed that the license will remain free for a minimum of five years. We do not have any plans to charge for a license but we do not want to preclude the possibility at a later date - well would you ? PD Authors : We gurantee that your license will *always* be free. Licensing the PCA standard allows us to keep track of who is using it, inform them of changes to the standard and provide support in the case of a problem. PCA Logo ======== The PCA logo may be used by licensed PCA developers to indicate PCA compliancy. Licensed developers must not use the logo to suggest any Clares approval or branding for their products. Contacts -------- DJackson@clares.demon.co.uk - Licensing details and project coordination. rdavison@xtra.co.nz - Author of the standard. Disclaimer ========== This standard is supplied 'as is'; neither Clares nor the author of the standard make any warranty, whether express or implied, as to the merchantability of the software or standard or its fitness for any purpose. In no circumstances will Clares or the author of the standard be liable for any damage, loss of profits, goodwill or for any indirect or consequential loss arising from the use of this standard or software. Implementation of the standard is deemed acceptance of these terms. PCA Compliant examples ====================== This disc contains several examples of PCA applications in both C and BASIC. They show different interfaces that can be used as well as an example of 'In-Place' editing. Don't forget to let us know what applications you are writing to comply with the standard. Clares may be interested in publishing any PCA applications that you write so please send us a copy if this appeals to you.
