The Sharp ER-A242 cash register was way ahead of it's time but sadly is no longer made. As a matter of fact no Sharp model cash registers are made any longer. We can still offer limited support for the Sharp ER-A242 over the phone for programming and troubleshooting.
For a new register you can replace a Sharp ER-A242 with a SAM4s ER-260EJ model for as close as you can get to the original. There are several other options available too, for the best match call us at 800-863-2274
