The DEC [[PDP-6]] and [[PDP-10]] had LUT2-style Logical operations covering the full suite of 2-operand logic{{sfn|pdp10|p=2.38|at=2.4 Boolean Functions|}} [[Boolean function]] instead of ternary, like AVX512 and Power ISA. Later models of the PDP-10 had instructions to covert between [[Binary-coded decimal#Packed BCD|packed BCD]] and binary.{{sfn|pdp10|pages=2.99|}}
Also present is unusual (variable-bit-length) load and store instructions. Both the bit length (S) and the offset (P) could be specified.{{sfn|pdp10|pages=2.85-2.89|loc=Byte manipulation|}} The Byte Manipulation instructions[2] can specify a byte size of 0-36, but may not straddle word boundaries. The String Manipulations have a similar restriction.{{sfn|pdp10|pages=2.91|loc=2.12 String manipulation|}}
