[SunRescue] Sun 3/60 bootable tape drives?

[Reagen Ward]

I just had two Sun 3/60s dropped off in my office.  They both have 12MB of RAM,
and no disk.  Also included was a tape with SunOS 4.1.3U1, and the tape looks 
like a TK / DLT type cartridge.

What kind of tape drives are bootable?  Should I just get the old SunOS distro
and netboot instead?  Please excuse me if these are in a FAQ; I'm very lazy.
