It was never really clear to me if the "Hornet" was a custom design Intel did for HP or if "Hornet" was just the codename for the 80C186EA, a 186 with added powersaving support. Either way those palmtops were quite cool machines.
REP BOUND only compares against lower bound
REP MUL result in AH (byte) or SP (word)
REP IMUL result in CH (byte) or BP (word)
REP IMUL reg,r/m,i16 first operand ignored, 32 bit result in DX:AX
REP IMUL reg,r/m,i8 first op ign., AH=result bit 23..16, AL=bit 7..0
AAM 00H no "divide by zero" exception, AH=FFh, AL unchanged
