There is a nice wiki in Amstrad CPC style with a lot of useful features. You can see and test it here:
https://en-web.eu/cpcwiki
There is an email address on the start page (decode it with rot13) to get a copy of the wiki source which is written in php.
Any chance to output it in 8bml so it can be viewed on cpc with suitable browser?
Probably yes. but please give me more information about 8bml - what do you mean about this?
