As I previously said, I can burn you a copy of both v3.5L EPROMs but the GAL chip (a smaller IC) that's needed to enable the EPROMs cannot be copied. It's a copy protection system on a chip. And you must have v3.0 of the GAL in order to be able to use the v3+ EPROMs. :-(
Plus, I don't own nor need a LARC, and so I don't have any corresponding cables...
But if you still want the EPROMs, like I said I can send you a copy of both. PM me if you're interested. Hope that can help...
