The TK50 specification lists a design lifetime of 30 years for TK50 tapes. Some of the older tapes in my collection are starting to approach this age, so I think it's important to create a digital archive of these tapes before they become unreadable.
After some searching, I found some code to create tape images compatible with the SIMH emulator. This code successfully compiles on a CentOS 5.4 system, and works with the /dev/nst0 device. Using this code, I made the following images of my TK50 tape library.
