Yikes! I've been thinking, since the Previous (NeXT) emulator works so
well, what would it take to turn it into a Sun emulator? I haven't looked
at the Previous source yet, but it seems like that would be a good starting
point.

Yes, the Sun compiler. At some point, I'll see if I can get my 3/60 booted,
but I'm lacking the right SCSI cable, I think. I also don't know how well
SCSI2SD will work emulating a streaming tape device, if at all.

Does anyone have a 3/60 hard disk image of SunOS 3.4 or 3.5, by chance?

Thanks,
