An advanced concept in calculating power

Wang calculators are as convenient and portable as Many companies are standardizing on Wang calcu­ a telephone. There is always space for the compact lators because the versatility and compatibility of keyboards wherever greater computational power the 300 Series can solve the needs of a variety of is needed. They are as simple to learn and operate operations. As explained on the following , as a ten-key adding machine, yet they can increase there are many options available (more than any computational speed by as much as 8 to 16 times. other calculator manufacturer) to increase calcu­ Because there are no moving parts, all computations lating capabilities to suit every need.

Basic Model 300K keyboard and separate, compact electronics package 300E (shown at left) is the standard configuration for single UP TO 200 FEET APART unit applications.

Up to four 300K keyboards can operate simultaneously from electronics package 300SE (as shown at right) for greater economy in multiple station applications. Line connections are provided in 25 foot increments up to 200 feet.
