What's keeping the IRQ7 occupied ?

Found a bunch of trainers 😁

These trainers do not always help on real machines. especially if they are faster than 200mhz.
This game is a tricky-one. Slow machines do not work with sound (mostly), faster ones do work, but the caches have to be disabled otherwise "Überlauf by Division", but deactivating the caches leads to stuttering gameplay. What a game!

I have to admit that I really like the game. Gfx-scolling, music, everything is excellent. Packed into one floppy...excellent, but the technical issues of the engine...

Does it work without a soundcard ?
