Acorn Internal Development Doc (early 80s)

Postby stmuk » Mon Dec 04, 2017 7:38 pm

I was given back in the early 1980s a stapled A4 photocopy what appeared to be a leaked internal development doc about the BBC Micro from Acorn (complete with "do not distribute").

This contained a wealth of information which was at that time hard to find. I mainly remember a fairly complete list of *FX type calls and docs about the ROM API (OS calls) which had me quite excited at the time -- basically the same sort of information which later appeared in more detail as the "Advanced User Guide" which made it obsolete. I always assumed the authors may have started with it and expanded the information.

Does anyone recall this document or even still own a copy (even as PDF)?

That would be an interesting read! Did the 'faults' mechanism fall away? I'm aware of 'events' but not 'faults' - although we do have 'errors.'

That section just describes the use of BRK to generate error messages.
