I can easily grant you access to mine. It's a bit slow but you can quickly poke around with the state in the backtrace which honestly looks to me like it should be enough to spot the problem.

There are other options. There's a good emulator at http://simh.trailing-edge.com/ and there are other non-ieee platforms out there. But installing an OS is a bit of a hassle.

If you're interested send me your email address and preferably a public key or something and I'll send you a login.
