The Triple Tech, as the name implies, is a 3-in-1 card for the TI-99/4a. The card has a real time clock/calendar function that is accessible via BASIC or XB through file commands like Open, Print, etc. The card also has a 64k print buffer that helps in freeing up your computer faster. And finally it has a port, like the Rave99 Speech Adapter, that allows you to take the circuit board from your TI Speech Synthesiser and insert it onto the card and in the PEB. An interesting side note is that this is one of the first cards that shipped bare, without a clam shell.
