In this week's On Call, Ryan recounts his experience with Wang Laboratories' desktop calculators during a field service call. When arriving at a customerâs site, he found the office closed and makeshift trailers in its place. Upon investigation, he discovered that the calculators were malfunctioning not because of a defect, but due to a low voltage of only 64 volts from the power source. This anecdote highlights the challenges of supporting older technology and the importance of power supply in device function.
Ryan later chuckled, recalling that he had to explain to the customer that their calculators were working fine, but they weren't receiving adequate power.
Field service for older technology presents unique challenges, as seen in Ryan's experience with Wang Laboratories, where power issues led to a cascade of malfunctioning devices.
