I'm running it on the real deal - a 1991-ish SPARCstation IPC. 25MHz of SPARC goodness. Most of these machines are dead because the power supply output capacitors have failed, but a fairly easy soldering job and they are back up and running. My original SCSI HD also failed (a 424MB Seagate ST1480N), but I've subbed in a SCSI2SD. Works a treat. I basically just play Nethack on it. I've also been experimenting with TeX 3.141 on it. As far as a VM, I believe it is possible to run 4.1.4 within QEMU. I haven't personally tried, but I have had success in the past running some versions of Solaris 2.x for sun4m in QEMU. I believe you can emulate a SPARCstation 5 with tcx graphics fairly well with that.
