LFSR is "Linear Feedback Shift Register". It is a method for
generating
pseudo-random numbers using special circuitry to cycle through a
very
long repeating pattern. These are not complicated circuits, so I
don't
know what this alleged imperfection is.
I'm extremely skeptical of this claim. However, it would be
relatively
easy to determine whether aces show up too frequently, and if this
claim were verified I would think the manufacturer would have some
major explaining to do. At any rate, it would be ludicrous be
believe
that all machines from all manufacturers have the exact same design.
I'd even be surprized if they all use an LFSR.
I agree wholeheartedly. If you must include a microprocessor in the
system design then using a software PRNG is easier and less
expensive.
I believe all modern VP machines have microprocessors to handle the
game itself, record keeping, diagnostics, configuration options,
etc., etc.
