the output on the c20 does not even light to indicate it is on. But the same program in the CPM1 works fine. All outputs work.

Thanks for the help. I copied the program address by address into a CPM1 processor and found the program to work correctly. Problem must be with the processor. bad ouput

Hi I have a print out of an old c-20K file *.swp and the I/O numbers I see on the print out don't seem right. Instead of out puts 5:00 to 5:07 and inputs 00.00 to 00.12 I seem to have I/O of 001.00 series 002.00 ;003.00; 004.00; HR which is know as holding relay internal (right?)
