Yep, IIRC, it was a 4 bit processor because 4 bits is what it takes to represent one decimal digit.
That was the Saturn, first used in the HP-71B. The original architecture (known as the "Nut")was weirder than that. It operated serially on 56 bit words (14 BCD digits), and the instructions had options for operating on various fields of a floating-point number (mantissa, exponent, sign, etc.) -- Greg -- https://mail.python.org/mailman/listinfo/python-list
