Subject: TubeSilencer

TubeSilencer is a new piece of hardware that helps in
connecting the beeb's Tube interface to modern hardware
development boards. It converts Tube signals from 5V to
3.3V, or even lower voltages. See :

Besides being 'general purpose', it will be needed to use
my pending release of the 'soft' Acorn 6502 Second Processor
for the Terasic DE0 Nano, which will enable it to run at 50+
MHz. See (previous) DE1 port here :
