BTW, I noticed a couple of places in DTF.MAC where error checking code was
commented out, e.g.:
;EHLT4: XX ;HALT WITH BLK#IN LIGHTS, CONTINUE
; MOV #257.,R0 ;TO FIND DATA WORD POSITION
; ADD TOG1,R0 ;DETERMINE WHICH WORD IS WRONG
;EHLT5: XX ;HALT WITH #OF WORD IN LIGHTS. 0=REV. CHKSUM
; MOV @TCDT,R0 ;CONTINUE TO FETCH BAD WORD
;EHLT6: XX ;HALT WITH BAD DATA IN LIGHTS. CONTINUE
Maybe it would be useful to un-comment them?
No, this is the old code to display the error words in the front-panel
display. Instead, my code (that follows the commented one) converts the
words to ASCII octal representation and displays the appropriate error
message on the console.
