HP 7470A Plotter

The 7470A was the world's first small format paper-moving plotter. Previous plotters held the paper still while a mechanical arm held a pen to draw a 2-dimensional image. The advantages of the paper-moving technology were: lower costs due to fewer mechanical parts, higher speed due to the much lower inertia of the moving parts, and smaller size. The 7470A was a two pen plotter that plotted on A4-size media. It offered three interfaces: HP-IB, RS-232-C and HP-IL (for connection to HP handheld computers). The 7470A replaced the 7225A.

The HP 7470A and 7475A provide hardcopy computer graphics
for technical, scientific, and business applications. Colorful A4/
A-size charts and graphs are ideal for reports and overhead trans-
parencies. Use them for summarizing data, identifying trends, com-
paring results, and focusing on exceptions. The larger A3 / B-size plots
that can be drawn on the HP 7475A are particularly useful for time
lines, PERT charts, schematics, engineering drawings, and other ap-
plications where you need to show visual detail.

Our machine has a serial number of 2308A 51151
