i am looking to buy a pc interface for cash register tec ma-1350 with softw?

Hi. You don't have to have an interface to program it. You can program the machine directly. If you want an interface, you'll have to see a local dealer.

if you want to program it from the register's own keyboard, there is an operting / programming manual here:
