But IIRC Tnix is simply AT&T Unix version 7 with
bits taken out and
other bits added on, so fsck should be the standard Unix v7 fsck for the
PDP-11. I suppose that could be found elsewhere? Or would it have been
modified to suit Tek's hardware?
If, as others have said, fsck was a standalone program on this machine,
it must have been modified for the hardware. The Tektronix disk
controlelr is nothing like anything DEC used AFAIK. IIRC it's actually
the standard Micropolis controller (which mounts on the drive itself)
cnnectred to a Tektronix bus interface.
