There were a few occasions when the Extel machine was innocent when an "All the pictures keep jumping" fault was investigated.
The electronic calculator was in its infancy and machines like this were used in large numbers. That is manually operated and relatively small compared with many I encountered.
A roomful of them all driven by un-suppressed electric motors could really create a lot of RFI! (And noise!)
