- Looked OFF to me. The fan was off, and it didn't blow up, so that
- pretty much says that it was off. (the memory board had something
- like 72 dynamic memory chips... And there were TWO of them...)
- The power light was off, everything was off. The startup was a cold
- restart from the beginning.
- The Lisa had no battery-backed-up RAM, so it did need to be
- plugged in all the time.

- The Lisa was like these-- I suspect there was seperate circuitry which
- did nothing but count down and trip the relay when it reached zero,
- provided you didn't press the power button before then.

- But it was VERY eerie...
