I lack success in getting the original yellow labeled Datacad 10 disk and V 9.5 parallel hardlock to work in Ubuntu. Here's what I've done so far:

Obtained the aksparlnx hardlock device driver source code from Alladin. Able to compile it into a machine specific loadable device driver to load with modprobe aksparlnx.

Obtained the aksusbd harlock installer from Alladin. Converted the .RPM package installer to .DEB with Alien. Can get aksusbd daemon to load.

Obtained winehasp.zip from Alladin. It contains winehasp.exe. This is supposed to allow protected programs to run under Wine. Can load winehasp.exe with Wine. It also contains the WIN32 HASP HL API. This would presumably replace the API that Datacad uses and supplies. I think they would have to link it in to be able access it. It is supposedly universal for Wine or Windows and automatically detects which. Otherwise, I don't know how to implement it.

The versions of software that I've been working with on this are: Ubuntu 7.04, Wine 0.9.50 and Windoors 0.9
