Yes I have it too. It's called 'The Octamed Companion - A Complete Step by Step Tutorial for OctaMed v5'. There's about 220 spring-bound pages of poor quality typed text with a cover that's more of an 'Amiga buff' than orange. Three disks came with it when published by RBF Software in 1993. RBF is Ray Burt-Frost who collaborated with Teijo Kinnunen and many others to create the OctaMed phenomenon.
There is no doubt that this booklet is essential to anyone wishing to understand the complexities of the OctaMed series. You can certainly learn a little by 'reverse engineering' OctaMed modules, but 90% of the codes you see on the player interface are complete gobbledygook without this Tutorial to explain them.
The manual is of course copyrighted, so publishing a PDF version would be naughty. However, how the heck can today's Amigans hope to keep the OctaMed dream alive without bending the rules a little? I wish I had the time to do it, but I don't.
Maybe someone will....
