Yes, I got carried away. The Apteva is a 32-bit system and supports
only simple single-precision float arithmetic. That's old skool. 
Only 1 GB RAM. The feature that still appeals is that it dissipates 
a mere 5 Watts. OTOH, my current graphics hardware performs abysmal 
(with 2D tasks).

Off-topic: how much fan-noise do current high-end graphics cards make?
