/* Dallas Semiconductors Smart Watch */
The 28pin '''Smart Watch''' (DS1216) is an adapter that can inserted in standard ROM sockets, a ROM chip can be mounted piggyback on the adapter, inside of the adapter is a 16pin '''Phantom Time Chip''' (DS1315). Normal memory reads are forwarded to the piggyback ROM. After reading from a specific sequence of addresses, the ROM is disabled, and data is instead read from the Phantom Chip via 1bit databus. Writing to the Phantom Chip is done by reading from a specific sequence of address, too.
