I'm pleased to say that the old R51 is now a pretty capable - if a little pedestrian - 3D printer control box at Protolab. It's running Lubuntu 16.04LTS, which is surprisingly nice. On 2016-04-24 10:29 AM, D. Hugh Redelmeier wrote:

All it needed was 'forcepae --- forcepae' at the end of the initial Live CD boot, and it picked that up for running and the installation.
How much RAM does it have? How much can it have? That's the main cause of machines becoming useless to me.
1.5 GB, and that's the maximum.
I don't have a feeling for ByteMark.
Sorry, I miss-spoke - it's byte-unixbench <https://github.com/kdlucas/byte-unixbench>. I wanted something that would test a little more than raw CPU speed so I could triage old machines.

Not a surprise. But sad / funny. Is there anything interesting about a Galileo? Is its performance respectable for its power consumption?
Not really. It runs Arduino sketches very slowly (like a few 10s of analogRead() calls every second). It draws about 15 W, and the fanless Quark SOC (400 MHz, Pentium Pro-ish, complete with FDIV bug) makes air above it shimmery-hot. It has no display capability. For reasons best described as "dunno", I have it set up with a mini-PCIe wireless card. It run Yocto Linux, which give immediately password-free access as root. It's twice as expensive as a Raspberry Pi, and gives an overall Byte Index of less than 1/4 of an original, single-core Raspberry Pi. cheers, Stewart
