Decodes tape images from the PDP-1X. This works with both micotapes and magtapes found here:

http://bitsavers.org/bits/MIT/rle_pdp1x/

Usage: pass "-u" for microtape, or "-m" for magtape. Pass "-t" to produce a file listing, or "-w" to extract tape file contents. Files are written as three sixbit bytes from each 18-bit word; i.e. much like a paper tape. Pipe the image to stdin.

There's another program to convert files to Unicode text, and one to convert a text paper tape to binary format.
