DAC-612

Serial: 207881

Based on info from Rick Bensene, this would be another repackaged Casio calculator. The logic and keyboard are that of the Casio 122 (see Onno’s Casio 122) with the 7-segment display replacing the Nixies of the 122. “Model 122” labeling can also be seen on the PCBs.

The display uses individual 7-segment gas-discharge display tubes.
