[Coco] So, my CoCo 3 may be having some trouble

Wed Aug 21 22:30:45 EDT 2013

Yes, I managed to get that from Google after I sent the message.  Turns out that it won't reload back into the original location, and it won't run from a new location (so I assume the code isn't relocatable)...  I'm now thinking it will need something that puts the coco into RAM mode and then reloads it back into the correct spot.  I'll see about capturing it in such a way that it will load up in an emulator -- such as it ever loads up so far -- shortly.
