Please explain again what the end program will look like and what it will 
be capable of.  I've always *loved* the graphical appearance of David 
Keil's emulators but the accuracy of the M.E.S.S. CoCo modes.  Being able 
to use the mouse to manuever CoCo hardware/disks/peripherals has always 
been on my wishlist.  :)

In fact, my IDE will eventually gain more graphical representation to make 
things even more easier.  For instance, it's quicker to see a floppy disk 
icon than to read the words "floppy disk", or an image of a ROM Pak would 
be much more appealing than the words.
