Just another plug: I have (so far) archived about 900 tapes (TK50,TK70
and magtapes) into TDF file format, which is basically a superset of
the wellknown E11/SimH "tap" format supporting tape label info (what
was written on the paper labels), block and file CRC checking, and
compression.

It takes E11 about a minute to fully install an ULTRIX-11 V3.2 tape
this way ;-)
