@Electronics Anyone have a suggestion on how to convert an LTSpice model to something that ngspice / oregano can handle?

I found a .asm / .asc schematic for the ULN2003 transistor array that I'd like to try out, but oregano doesn't seem to have a way to import it.

I'm willing to try other circuit simulators as long as they have a reasonable GUI. I already tried Qucs and it seems to be worse in this regard (and buggy in general).
