DAC-612<\/strong><\/p>\n

Serial: 207881<\/p>\n

Based on info from Rick Bensene, this would be another repackaged Casio calculator. The logic and keyboard are that of the Casio 122 (see\u00a0Onno’s Casio 122<\/a>) with the 7-segment display replacing the Nixies of the 122. “Model 122” labeling can also be seen on the PCBs.<\/p>\n

The display uses individual 7-segment gas-discharge display tubes.<\/p>\n\n\n\n
