7-24-3 LOGICAL OR – ORW(35)
I1
: Input 1
IR, SR, AR, DM, HR, TC, LR, #
I2
: Input 2
IR, SR, AR, DM, HR, TC, LR, #

DM 6144 to DM 6655 cannot be used for R.
When the execution condition is OFF, ORW(35) is not executed. When the
execution condition is ON, ORW(35) logically OR’s the contents of I1 and I2 bit-
by-bit and places the result in R.
