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

[Bill Pierce]

Chris,
The cart is not going to reload at the addresses it's saved from. You'll be reloading to a rom area and the Coco don't like that. It has to be converted to load from lower memory with a rom/ram loader. If you have a successful save, send it to me and I'll do the conversion and send it back. The whole idea (at this point) is to just get a successful cassette save and convert it to a wav file.

Well, I haven't been able to get the cart to save and then reload without an I/O 
error.  Not quite sure what's going on yet.  Small BASIC programs seem to work 
fine.
