Patches and discussion for Ensoniq VFX family

I'm not an idiot, but I have a really, really stupid question to ask. Can I use an Ensoniq ESQ cartridge in a VFX? I doubt they do, but I haven't had the guts to see if they fit. 

VFX carts are just so rare and expensive, I was wondering if there is an alternative (other than the floppy). 

Thanks. And please keep your mockery to a minimum.
