Many Thanks for the informations!
I have some special drivers (various versions) for the Lisa DAC- are these drivers suitable for the use with MacWorks XL 3.0?? There was no info file on these disks.
There is even a special version studio sound session bundled with these driver disks...

The Sound DAC crashes the Lisa when my Accelerator 18 is activated- so I have to deactivate the accelerator before using the Lisa DAC- would it be possible to patch the MW+II to solve this problem? One game : Creepy Castle is working excellent with the Lisa DAC- I havn't tested other games yet.

John W. is currently working on a new version of the Lisa DAC---- did you know that?

Another interesting topic- perhaps it doesn't fit in here: It ACTUALLY i s possible to LLF a Widget- my Widget has being Low Level formatted by a person who doesn't like to give away his knowledge and name - he is living near Seattle. Now I have fully functional Widget again.
I presume that he has purchased all the necessary materials and informations from Bob Cook , CEO of SUN Remarketing, which is no longer in business.
I hope that his knowledge, materials and informations won't die with him.....
Perhaps you have more informations than I do?

Helmut
