Adam,
Here is the console output from when I converted your .emu file to a .dsk extract file. It so exciting to know that someone actually has a 68K system running UniFLEX. My goal is to get UniFLEX running on one of my CDS68020 machines. Currently they are both running OSK (OS9 for the 68K). In case you did not know, the CDS68020 is also known as the PT68K-5.
