DirOpus v4.12 on Amiga (Workbench v3.1)
The screenshot was taken from WinUAE, but the system was ported 1:1 from my Amiga 3000 incl. Picasso IV (which explains the higher res compared to ECS). I've spent some hours to get it work (uncounted "gurus" ), especially some OS-updates were necessary and over the years I nearly forgot all about its configuration (last used in 1998, but the Amiga still works). Now I miss "startup-sequence" again in Windows .
You may ask why not DirOpus v5/Magellan? I didn't liked it with all its windows and it simply ran too slow on a 68030 .
