Loved my HP45. The young guys have been brainwashed by Texas Instruments, RPN is vastly superior!The SQ Position Encoder is an SQ encoder, each of the settings for a particular position set the phase and amplitude of the signals so that it would [SQ] decode at the desired position. A unique feature was "diagonal splits" which provided (IIRC) ~8 dB (LF/RB and RF/LB) rather than the ~3 dB of a regular 4 corner [only] input SQ encoder.
(I have a photocopy somewhere that gives the vectors, I worked thru them many years ago on my HP-45 to see what they meant by "diagonal splits")
