Info: Shortly after the introduction of the Heathkit IC-2008 Desktop calculator, Texas Instruments decided to discontinue the TMS1875 single-chip calculator circuit to focus on the more lucrative TMS0100 Product Family. And the IC-2008 was selling like hotcake, probably around 1,000 units per months at a typical price of $139.95 (around $1,000 in 2023 money) per unit. Heath needed a solution, and they needed the solution quick. Enter IC-2008A.

The first figure shows the state of the display upon power-up. Turning on a Heathkit IC-2008 calculator can take up to a minute for the display to become fully operational, and instead of the usual " 0. " display, the operator is greeted by a bright neon-orange " ooooooo0. " display. The third figure shows the state of the display after a division, with the decimal places set using the rotary switch above the 7.
