What is it
TubeSilencer converts the signalling voltage of the Acorn Tube interface from the standard 5V to lower voltages. Typically, it converts to 3.3V. Lower voltages (e.g. 2.5 or 1.8) are possible, should the need arise.
In addition to the regular 40 pin 'Tube out' connector (which has the same pinout as the 'Tube in' connector), there is support for a 20 pin 'Tube out' connector, which is plug-in compatible with several Terasic development boards (like the DE1 or DE0 Nano), i.e. it eliminates the need for an (additional) adapter cable.
TubeSilencer is compatible with all Acorn Tube interfaces.
More details, and more technical information, can be found in the actual TubeSilencer documentation. It may be quite helpful to read. You can download it on the 'Updates' page.
