So a story about core memory.
I was working with a group and had just finished bring up of a new system. It was running the diagnostics when someone in shipping turned off the hardware. No disk so no risk of breaking something like that (ah those were the days). Anyway they pack the machine and deliver it to the customer (name lost to the mists of time) who gets it set up and then powered on.

It resumes the diagnostic. The customer was amazed that the machine would perform a diagnostic on power up. Though that was the most wonderful idea.
