You'd have to be crazy to do this instead of using -current. You really want to have to do two ports instead of one? That's what you'd effectively be doing. > Something interesting to do would be to design a virtual machine on an x86 > freebsd machine, obviously a C compiler also then port to that virtual > machine. In fact I think I'll do this! There is a project under way to do something like this for MIPS, PPC, and SPARC (it's much less ambitious; the idea is to let you run MIPS, PPC, or SPARC binaries on other architectures using processor emulation; the same goes for x86, using PCEMU, on non-x86 machines). If you are turly insane, a good project for the insane would be porting PCEMU to JAVA. 8-) 8-). There aren't any good, freely available 68030/68040 processor emulators, nor any good, freely available Alpha emulators, from what I've been able to determine. If you are just into writing an emulator, you may want to tackle one of those. Of the two, the 68040 would be *much* easier to do (IMO).
