Using the AstroBASIC 2000-BAUD Interface with Vipersoft BASIC
-------------------------------------------------------------

     This documentation discusses swapping AstroBASIC with Vipersoft BASIC 
loaded into RAM, either from a multicart, a cartridge created from an EPROM or 
from (probably the most common method) loading Vipersoft BASIC from a tape.  
This cartridge swap is done so that the AstroBASIC tape interface can be used 
to save or load to tape at the faster 2000-BAUD instead of requiring the much 
slower (and rarer!) 300-BAUD external interface.

     ViperBASIC on cart has a 'loader' routine in front to move it into the RAM 
where it expects to be.  As such, after it has 'loaded,' you can swap the cart 
for the AstroBASIC cartridge and use the interface just fine.

     If you reset the Astrocade while the AstroBASIC cartridge is in the 
cartridge slot, type 'CALL 24576' followed by pressing the GO key to return to 
Vipersoft BASIC.
