  Actually an abacus is more like one single integer register (or a few,
if you split the "bits" among several "registers"). It could only be used
to store and manipulate one value (or a couple) at a time. You would not
only need a processor to actually execute the raytracing opcodes, but you
would also need some external "RAM" to store intermediate results. The abacus
by itself is certainly not enough for any of this.

  (Not to talk that an abacus probably wouldn't have enough "bits" to do
any kind of sensible raytracing anyways.)
