If you need to have Super Extended Basic available on the CoCo 3, you can use
the same approach I used for Extended ADOS-3, which resides in a 27128.  When
you need to call a ROM routine that is in the upper 8K of your EPROM, you switch
to ROM mode first, and switch back to ROM/RAM mode on the return from the
routine (to somewhere not in the upper 8K) to re-enable Super Ext. Basic.  
(Have your ROM test whether it is running on a CoCo 3 during initialization, and
do this only if a CoCo 3 is being used.)
