Audiotap is a program for conversion between .TAP files and Commodore 64 tapes. It can read WAV files containing the sampled sound of a tape and convert them to .TAP files, and can generate WAV files to be recorded on a tape and used on a Commodore 64. It can also record .TAP files from the sound card and turn .TAP files into sound played to the sound card. It does not require custom-built cables, just plain audio cables connecting the sound card and a normal audio tape player/recorder.

Cloonix is a Linux router and host simulation platform. It fully encapsulates application, host, and network l2 and l3 into a relatively easy-to-use simulation GUI. Network delay and loss characteristics can be configured per link. It provides support for running kvm or UML virtual machines configured into an arbitrary complex network configuration. It is possible to run a 12 router UML simulation on a small x86 host (a P4 with 512 MB RAM). 32- and 64-bit KVM machines are provided.
