I'm not a low-level hardware person, but I do know the Amiga and PC parallel port pinouts are different. I think the PC also lacks the +5V line used to power devices like the DSS8.
I understand your desire, though. The DSS8+ is pretty clean, but some of the older devices produce a distinct and cool aliasing effect. A lot of the samples used by Kon Kan and other similar bands from the 80's have that feel.
