As I have said several times, if you want to learn how a computer really
works, buy a non-working Unibus PDP11 (nto an 11/24, 11/84, 11/94, etc
,one of the TTL-baed ones), a PDP8/e or an HP9830 and learn to fix it. By
the time it's working you will know just how a CPU executes instructions.
If you are prepeared to use a microprocessor, then get a BBC micro. I've
yet to se a better educational machine. Seriously.
But I do wonder jhsut who the Rpi is aimed at. Given that you need a PC
and its peripherals (keyboard, mouse, monitor) to use the Rpi, I wonder
if it wouldn't be simpler jsut to install a free C compiler on said PC,
at least to learn programming.

There are, IMHO, 3 thigns wrong with the Rpi. The
hardwre, the software,
adn the docuemtnion.
I think my main problem with it is that I'm tainted by nostalgia, and what
I really wish it was is a backplane system with separate cards for ROM,
RAM, CPU, I/O, video etc. :-) Much more fun to mess around with, put into
a cool-looking chassis, use to teach kids about how a computer works etc.
