If you SSH to 3b2@sdf.org, you can find your way into an emulated

first porting uuencode to it, and then porting a version of tar that
you can also run someplace else. The tar that's installed on the
system is not compatible with modern tars, nor is it compatible with
V7 tar.

Something is wrong here.  A PDP-11 running SysV?

That surprised me too, but Wikipedia tells me that SVR1 ran on PDP-11
and VAX.

It doesn’t seem to work very well on this emulator however...

And with the uid "3b2" also?  And this isn't an AT&T 3B2 running SysV?

3b2 is just a username, the menu system offers a range of platforms.
