I'm in need of help, and as part of a bribe before I go and compose my question, I have 10 page scans from several issuies of an old(ish) magazine. Practical Computing 1985. These are three of a four item series about the Beebs OS. Inside OS, (Sub-heading is "Roger Cullis dissects the BBC Micro's operating-system ROM routines.") Further along in the text a reference is made to a book that was to be published detailing all this and more by Losco Ltd. I have never seen the book, nor have I found it in my brief searches. Needless to say tracking down the missing issue of Practical Computing to complete the series has been even less fruitful.

As a few of the forum entries mention OS entry points, OS tables and such like, this may prove of more use to some of the more prolific programmers out there than the space it is taking up on my hard drive.

I went to plug it into the 'Useful Docs' page but I don't see which heading it would be suitable under. Any ideas?

If the complete series is already available somewhere, or you know where the book is, any chance somebody else might be able to throw up a link and save me wasting your bandwidth?

File is roughly 1.3MB zip file of a PDF. 10 pages, 300dpi b/w.

Obviously, a complete book or series of mag scans would be preferable, but uploading a file that size isn't going to stress the wiki so, if you can't track down any more info, feel free to upload your scans if they will help others. You can always upload now and replace the information with full scans if they later become available. That's the great thing about wikis ...

Not directly what you're after, but there was another series about the OS on Micronet including a discussion and an annotated disassembly, which has been archived on TBL. There are some bits chopped off the end of files (in particular the OSWRCH entry point at &E0A4) and J.G.Harston has made replacements in his copy on MDFS.

HTH.
