Popis instrukce, nebo lépe instrukcí třídy operate.


100 000	CLL	Clear left nine digital positions of the AC.
40 000	CLR	Clear right nine digital positions of the AC.
20 000	IOS	In-Out Stop. Stop machine so that an In-Out command (specified by digits 6,7, and 8 of MAR) may be executed.
30 000	HLT	Halt the computer.
7 000	P7H	Punch holes 1-6 in flexo tape specified by AC digital positions 2, 5, 8, 11, 14, and 17. Also punch a 7th hole in tape.
6 000	P6H	Same as P6H but no seventh hole.
4 000	PNT	Print one flexowriter character specified by AC digits 2, 5, 8, 11, 14, and 17.
1 000	R1C	Read ine line of flexo tape so that tape positions 1, 2, 3, 4, 5, and 6 will be put in the AC digital positions 0, 3, 6, 9, 12 and 15.
3 000	R3C	Read ine line of flexo tape so that tape into AC digits 0, 3, 6, 9, 12 and 15. Then cycle the AC one digital positions; read the next line on tape into AC digits 0, 3, 6, 9, 12 and 15, cycle the AC right one digital positions and read the third and last line into AC digits digits 0, 3, 6, 9, 12 and 15. (This command is equal to triple CYR-R1C.)
2 000	DIS
2 000	DIS	Intensifi a point in the scope with x and y coordinates where x is specified by AC digits 0-8 with digit 0 being used as the sign and y is specified by AC digits 9-17 with digit 9 being used as the sign for y. The complement system is in effect when the signs are negative.
400	SHR	Shift the AC right in place, i.e., multiply the AC by 2^-1.
600	CYR	Cycle the AC right one digital position (AC₁₇ will become AC₀
200	MLR	Store the contents of the MBR (memory buffer register) in the live reg.
100	PEN	Read the light pen flip-flops 1 and 2 into AC₀ and AC₁.
4	TAC	Insert a one in each digital position of the AC wherever there is a ine in the corresponding digital position of the TAC.
40	COM	Complement every digit in the accumulator.
20	PAD	Partial add AC to MBR, that is, for every digital position of th MBR that contains a one, complement the digit in the corresponding digital position of the AC. This is also called a half add.
10	CRY
1	AMB
3	TBR
2	LMB
