9815A/S option ROM - Joel Setton (France) - 03-08-2011

Folks,

The option ROM which is built into the 9815 CPU board seems to contain some new instructions which are accessed via I/O select code 7. These are probably documented in some manual, but where? Has anyone seen this manual, or experimented with these new instructions?

Many thanks to all!
