No boot ROM means that a hardware device constructed from discrete logic and analog chips directly demodulates digital data from the radio, addresses the memory, and writes the data. Once this process is completed, it de-asserts the RESET line of the CPU and the CPU starts executing from an address in memory. Really no ROM!

Yeh, Aussie Rules and rugby are much more interesting!

I spent a year in the US when I was a kid - I lived in SF the year the 49ers won the Superbowl. So I had exposure to it at an early age and got caught up in the excitement of our American-living family & friends, which lasted for several years.

I stopped watching it for a while - mostly because of time differences and difficulty getting access to games. I moved to the US for two years recently and was looking forward to keeping up with it, especially while in a big college football town (Columbus OH). I went to one game and left at 3/4 time because I couldn't stand it any long; we were there for like 3 hours, it was something like 40-0, and just unwatchable. Atmosphere was amazing through with so many people.

You hit a LSB and something is off by one. You hit a MSB and you're potentially off by trillions.

That's a good argument for Gray code.

I have to take issue with the assumption that nothing clears errors better than a hard reset. There are very many known strategies for dealing with errors on a running system, and a reset only clears persistent and cumulative error, rather than transient ones. Since we can assume that your computer doesn't keep the same data in memory all of the time, most will be transient.
