Where to find a copy of Venus 1500 Version 2? Daktronics seems to have completely disowned it.

I'm mainly into collecting signs for historical preservation, but that means sometimes running software that is impossible to find. I can't seem to come across a copy of Venus 1500 Version 2 but I feel like there might be some users here who have been operating older signage networks and may be able to help me out. I'm not a big company that Daktronics would see as a valuable contract lost to legacy products, I'm an individual hobbyist so there is really no danger in giving me a copy of this software.
