I don't think you know, but the IBM 4694 has a P!!! 600 (or 700, I don't remind exactly) on his highest configuration available (at the time I've stopped to repair it for IBM). So this little Celeron
In the other hand, the price is INDEED not the same ^^ it's a shame to know how expensive can be a complete cash register, with peripherals (TI4 thermal printer, 4694 standard keyboard, scanner, cashdrawer, and all the IBM wires to lonk all that) ... I think it's between 6000 and 10000$, at least.
