Victor 4900

4900 was a machine in a line of Victor's 4000-series calculators. The 4000-series machines were desktop programmable calculators, with a 5x7, 110 character per second dot-matrix printer, and a built-in magnetic card device for offline program storage/retrieval. All of the machines in the line have two standard accumulating memory registers, 14 digit capacity, with up to 13 digits behind the decimal point. The mag card unit may store both program steps and memory register content. Additional memory registers range from a low of 6 on the model 4500, through 102 on the 4800. Program memory varied between 128 steps on the 4500, and 1000 on the model 4800.
