Hey, I know how to fix that. Old story, new IBM 370/158 installed by third party. IPLed 158 and it ran for a few hours and then died. IPLed again, same thing. Third party CE attempted to diagnose the problem. After several hours, the third party gave up and agreed to pay for IBM to diagnose the problem. Local CEs unable to diagnose the problem. Problem escalated to level 1 & level 2. Still no solution. After 24 hours of this, IBM flew in one of the 370/158 engineers to the site. The engineer asked to IPL the 158. After a short time it died. The engineer walked to the back of the 158 and removed the panel. After a few minutes, the engineer said there was a wire that was too long. Everybody on site thought "yeah right". The engineer created a shorter cable and installed it. The 158 was IPLed and it ran without a problem. The IBM engineer stated it was a "timing problem" because a signal was supposed to reach its destination in x microseconds. Due to the cable being too long, it was taking x + y microseconds.
No, this is not an urban legend, it really happened. "Confidentially doc, I am the wabbit." Bugs Bunny Sent with Proton Mail secure email.
