SDF’s 9 track tape drive

This tape is a small 600 ft tape at 6250 cpi for about 44mb uncompressed. It was written in cpio format. At the time the main root disk was 40 mb but I bet that /usr is really just a back of /usr/local. /pub used to be /usr/pub but was later migrated to its own filesystem on another disk. Today those files are in the anonymous FTP directory. Made in 1992, donated by M/A/R/C in 1994 and used regularly until 1996, and as needed thereafter until 1999. It was superseded by a 2GB EXAbyte 8mm cartridge drive.
