This Fujitsu/ICL system for post offices clearly had some major failing in it.
But does anyone know what it was? General journalism isn’t likely to tell us and the computer press might not go into the details of the accounting.
Post offices were being registered as collecting more cash than they had. That’s why post masters were said to owe the system money, or to have been skimming cash and all that.
OK, but what was the error of the cash counting system? What bit was it that went wrong? Was it doubling the amount that should be there for TV licences or something? What, exactly, was the accounting error?
