On my 3b2 310, you could always tell when the CPU were soaked at 100% utilization. The
main board would actually buzz.
If you entered a CPU bound job with bc for example, you would know when the result was
displayed on your terminal as the 3b2 would stop buzzing.

the only working Unix on display was running on a 3B2. Apparently
the machine was robust if nothing else.
