Advertisement for the Victor 4800 Programmable Electronic Calculator.
Scientific American, September, 1975

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 1973. The machines all used an impact 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 six function calculators (add, subtract, multiply, divide, square root and percentage). All of the machines had two direct keyboard access accumulator-style memory registers, with additional store/recall addressable memory registers. The 4500 offered 128 steps and 6 addressable memory registers, with no magnetic card peripheral. The 4600 was the same as the 4500, but included the magnetic card reader. The 4700 provided 512 program steps, and 52 addressable memory registers The top of the line 4800 as shown here offered 1000 program steps, and 100 addressable memory 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 These machines were superseded by the Victor 4900, a second-generation of the 4000-series machines, introduced in January of 1976. The 4900 added additional higher-level math functions, and significantly increased the number of program step and memory register storage.
