				KNOWEN PROBLEMS
				---------------
				      NONE


				   TECH	NOTE
				   ---------
   The TST module needs	to occupy both slots J5	& J10 on the T.I. motherboard,
   so if there a T.I. memory upgrade card in J10, it will have to be removed.
   before installing the TST module.
   If any of the memory	on the T.I. memory card	is socketed, that memory can
   be transfered to the	TST module.
