Rerouting sound (speaker/mockingboard)

[Linards Ticmanis <ticmanis@gmx.de>]

Hello,

I wonder if any schematics exist to

1.) Reroute the A2 internal speaker sound through a mockingboard to
external speakers. (My mockingboard is DIY concoction anyway so it is
modifiable.)

2.) Conversely, reroute the mockingboard sound into the internal speaker
so that no external speakers are needed.
