Advertisement for the Victor 4800 Programmable Electronic Calculator.

The Victor 4800 was the "top of the line" in Victor's first generation of desktop, programmable electronic calculators. Also included in the line were the 4500, 4600, and 4700, all introduced in the 1972-1973 timeframe. The machines all used a 5x7 dot-matrix printer (no display), and all but the 4500 had a magnetic card peripheral built in to read and store programs and data onto magnetic cards. Each magnetic card had two 'edges', upon which 128 program steps, or 16 memory registers could be stored. All of the machines were basic five function calculators (add/subtract/multiply/divide/square root). The 4500 offered 128 steps and 8 memory registers, with no mag card peripheral. The 4600 bumped the memory capacity up to 256 steps and 16 memory registers, and included the mag card reader. The 4700 yet-again doubled the memory of the 4600, with 512 setps and 32 memory registers. The top of the line 4800 as pictured here offered 1000 program steps, and 100 registers. List prices were $995 for the 4500; $1,295 for the 4600; $1,595 for the 4700, and $1,995 for the 4800. These machines were all superceded by the Victor 4900, a second-generation programmable, in the '74-'75 timeframe.
