[HECnet] Re: Weird microcode bug in the 11/60 CPU

Thanks for the pointer Johnny. Where might I look for the content of ECO M8782-00007? And 00006, 00005, ... Can you also point me to the RSTS/E "fancy" source :->? -----Original Message----- From: Johnny Billquist <bqt(a)softjar.se> Sent: Wednesday, February 2, 2022 7:16 AM To: hecnet(a)lists.dfupdate.se Subject: [HECnet] Re: Weird microcode bug in the 11/60 CPU Paul already mentioned it: Here is the code in RSX: [11,10]SSTSR.MAC: CLR @$CPUER ;CLEAR CPU ERROR REGISTER .IF NDF M$$EXT NOP ;THIS NOP MUST BE HERE. ;UNLESS THE MICRO CODE BUG IN THE ;11/60 IS FIXED (ECO M7872-00007), ;CLEARING THE CPU ERROR REGISTER ;WILL CAUSE THIS WORD TO BE SKIPPED. .ENDC (it actually occurs in two places in the code) RSTS/E seems to be a bit more fancy and actually tries to detect the bug and print a message on the console at boot (I assume) if it is spotted. I thought I had seen something in 2.11BSD as well, but now I can't find it.
