[HECnet] RT-11 on a PDP-11/10

Please send me content of memory block where program traps. Something like that:

--
?MON-F-Trap to 4 001012

..E 1000-1040
012700 123456 005727 000241 000000 000240 000404 040004
000000 000000 001032 000167 000422 045640 000020 000000
000001

.

Or you can use DBG-11 to debug the program:

.REN SDH.SYS SD.SYS

.SET SD SYSGEN

.SET SD REG

.INS SD

.LO SD

DBG Y01.16 - RT-11  ( SOFT  PRO  SD:  GRH )
