Victor 4000-Series Electronic Calculators
One of the Victor 4000-Series Calculators
Victor's entry into the sophisticated programmable electronic calculator
A series initially consisting of four machines; the 4500, 4600, 4700, and 4800,
introduced in the 1972-1973 timeframe.
in sometime during '74-75, a more sophisticated machine in the series was
introduced, the model 4900. The 4900 offered 1792 program steps and 202
memory registers, and provided a fairly substantial selection of math functions.The machines print using a high-speed seven-pin dot-matrix impact printer.
All but the 4500 provide a mag-card unit for writing/reading magnetic cards
for offline program and data storage. All of the machines were
microprocessor-based, using Rockwell's PPS-4 4-bit CPU and support chips.
The museum is currently looking for the model 4500, 4600, 4700, or
