I downloaded Open Transport 1.3 gold from Macintosh garden and unstuffed the .sit which has the 4 Open transport .IMG disk image files.
I thought great, copy to my SD card for my FloppyEMU and install
I .IMG files in that .SIT are not compatible with floppyEMU. So I converted the .IMG images to DiskCopy 4.2 disk images and vwalla! I can now install Opent Transport from my FloppyEMU.
So if anyone would like the .DSK images of Open transport let me know and I will upload!
