* Add tests for the DiskII card This change adds basic read tests for nibble-based disks for the DiskII card and fixes a few minor errors. These tests are in preparation for refactoring. * Add write tests These are some basic tests of writing to nibble disks. In the process, one minor bug was found, fixed and documented. * Fix the write tests I misinterpreted something from Sather and thought that the high bit had to be set on the data for writing to happen at all. This is not true. Instead, there is a flux transition every time the high bit is set as the data is left-shifted out of the data register. The erroneous test has been removed. At the same time, I finally understand what `skip` does and documented that. * Add tests for saving and restoring Disk II state These are not exhaustive tests, but they ensure that some basic state is saved and restored.
