I've thought about that.
Or maybe some other SBC, one with two NICs, because the Beagle Board only has a single NIC.
But I also like the idea of just keeping it as it is and adding the PPS to it, by putting a GPS inside it. Or maybe using it to house my GPSDO?
It has a 250 MHz 64 bit processor, and although I am fairly sure that the current OS's which run on it don't use the 64 bit aspect of the processor, its possible that some of the renewed interest in MIPS will lead to more options there.
It was very much ahead of its time when it came out (I'm its second owner) but now its very old. Even when I bought it it was old and outdated.
However its built like a tank, ran for years without a hiccup, takes little power, has an RTC, real hardware interrupts and non-USB NICs, its RTC keeps excellent time, has an interesting CPU architecture, and its a really pretty color.
