As the Pioneer spacecraft were launched in the early 1970s, their instruments were almost certainly a product of mid 1960s technology. That was an era where slide rules still ruled and mainframes were larger than a house but had less computational power than your toaster oven.

Timeline for Why was the imaging quality of the Voyager probes *much* better than the Pioneer probes despite being launched only 5 years later?
