macADT and .dsk images over 140k

[touchstone]

hi,

i have an apple iie connected to a g3 all-in-one (remember those) 
running os 9.1.
it works flawlessly with images of exactly 143360 bytes, as you would 
expect.  i've been
downloading the images from asimov.net and some of them that i would 
like to try
expand to 144k or 143363 or thereabouts.  of course, adt on the iie 
won't  accept any extra
bytes over the capacity of a floppy.


any ideas?  i've set the type and creator correctly and it's not a custom icon.
i tried to copy/edit these images on a iie emulator using blank 140k 
images, to no avail, using
an app called 'iie' found on the asmiov archive.

thanks in advance,

matthew
