The chip (actually a circuit module in a DIP socket) is the Dallas Semiconductor
DS1216E SmartWatch. There is public domain software, written by TransTech in
San Diego, that will use the SmartWatch in any ST rom socket (including
cartridge sockets). TT was selling them for about $25 a while back. I
don't know if they're still distributing them, but you can try calling them
at (619) 283-9328.

Caution: it is physically impossible to install the DS1216E in a 1040ST
without cutting into the power supply bracket. The bottom of the pan
just clears the tops of the TOS roms as it is.

Alternatively, Radio Shaft will sell you a SmartWatch locally, sans Atari
software, at a considerably inflated price.
