Subject: beeb RTC

On this subject I have already built one, and it did work, though it was a
bit touchy due to my rather poor PCB. It fits into the speech socket and
uses the RTC chip used in the Master and many other machines. My design has
a battery on it, and a few bits to support the battery and my glue logic.

I have in my draw a device made by dallas Semiconductors which is pin
compatible and includes a battery and all the crystal circuitry inside it.
This means I can do away with about half of the board are and bits.

Is anyone interested, since if they are I will persue it a bit more?
