PDP-10 Instructions

MOV - Move full word between accumulator and memory.

  MOVE* - Move without modification.
  MOVN* - Negate source.
  MOVM* - Magnitude (absolute value) of source.
  MOVS* - Swap source upper- and lower-half words.

  MOV*  - Move from memory to AC.
  MOV*I - Immediate. Source is value of E itself.
  MOV*M - Move from AC to memory.
  MOV*S - Move from E to E.

EXCH - Exchange values of AC and E.

JRST - Unconditional jump.

JUMP[c] - Compare AC to zero and jump to E if condition met.

AOJ[c] - Add one to AC, compare result to zero, and jump if condition 
         met.

SOJ[c] - Substract one from AC, compare result to zero, and jump if 
         condition met.

AOBJ - Add one to both upper- and lower-half word of AC and jump.

  AOBJN - Jump if AC is less than zero.
  AOBJP - Jump if AC is greater than or equal to zero.

SKIP[c] - Compare contents of E to zero and skip next instruction if 
          condition met. If AC is non-zero, set AC to contents of E.

AOS[c] - Add one to E, compare result to zero, and skip next
         instruction if condition met. If AC is non-zero, set AC to
         contents of E.

SOS[c] - Substract one from E, compare result to zero, and skip next 
         instruction if condition met. If AC is non-zero, set AC to
         contents of E.

CAM[c] - Compare contents of AC and E and skip next instruction if 
         condition met.

CAI[c] - Compare contents of AC to value of E (immediate) and skip next 
         instruction if condition met.


[c] - Arithmetic conditions for jump and skip instructions (JUMP, AOJ, 
      SOJ, SKIP, AOS, SOS, CAM, CAI).

  blank - Never jump/skip.
  L     - Less than.
  LE    - Less than or equal.
  E     - Equal.
  N     - Not equal.
  GE    - Greater than or equal.
  G     - Greater than.
  A     - Always jump/skip (JUMPA is deprecated in favor of JRST).
