I didn't know BMW made any cars with motors. There are some
programmable motors and programmable engines, but they tend to be
buggy, pricey, and not meet emission standards.

Doesn't the cpu in a mac go idle, at least part time, if you plug in a virtual
pc
card? In the C64, i think the 6510 went idle if you plugged in an 8085 or Z80
card. Someone once sold daughter cards for PCs that carried various cpus
too, and in some cases there was significant speedup,, but i grant you it was
all in hardware. Still, if someone with a 386 in Russia could plug in a cheap
1Ghz daughter card, it might be useful. The successfull breaking of RSA was
done on a PC, and the cpu did very little work, the real horsepower was in
the FPGAs on daughter cards laying all over the tabletop.
