Do you know enough about the 6702 checks now to modify the original binaries 
to bypass them?

I have a version of Waterloo microEditor where the check was removed by ISPUG 
members.  Before the 6702 emulation was added, I played around with microBASIC 
in VICE for a couple of hours.  I started tracking from _suicide and was able 
to get it to display the banner but it crashed before the prompt.  I've only 
been using the 6809 for a short time.

I'd really like to see the protection removed from the Waterloo disks.  On 
SuperPETs with 3 boards, the 6702 is on a daughtercard that is removable. 
Some SuperPETs may no longer have a 6702.  This includes one of mine; I 
donated its 6702 to be decapped and photographed.  The 6702 is also the only 
component preventing a SuperPET hardware replica.

Thanks,
Mike
