### "DeskTop" Application ### "DeskTop" Application
AUX $8E00-$FFFF (with hole at $C000-$CFFF for I/O and at $ED00-$FAFF for DeskTop application code is in the lower 48k of both Aux and Main:
data buffer) is the DeskTop application itself, with desktop and file
icons, menus, dialogs, and so on. * Aux $8E00-$BFFF - sitting above the GUI library
* Main $4000-$BEFF
And in the Aux language card area (accessible from both aux and main code) are relays, buffers and resources:
* Aux $D000-$ECFF - relays and other aux/main helpers, resources (menus, strings, window)
* Aux $ED00-$FAFF - hole for data buffer
* Aux $FB00-$FFFF - more resources (file types, icons)
($C000-$CFFF is reserved for I/O, and main $BF page and language card is ProDOS)
```
