[sdiy] Raspberry Pi 2 B Synthesizer Project Progress

[Sarah Thompson]

>From what I saw in an interview with Eben Upton, he was saying that they
really wanted the CPU because it ran 32 bit code much faster than the
previous Pi, but that they were going to do some experimentation with
running it in 64 bit mode.

PS: I know Eben from my Cambridge days, so it's always awesome to see the
Pi project doing so well. :-)
