When I posted my article about the J11 chip set, I left out one instruction from the diagnostic. This will cause the diagnostic to always fail (even on good chips). The missing instruction is a cfcc (Copy Floating Condition Codes) that should be between the cmpd (r2),ac0 and the beq 102$ I also discovered a couple of small errors in my transcription of the letter from DEC, the have also been corrected. I have reposted the entire (corrected) article to net.sources.bugs. I'd like to thank Paul McKenney (mckenney@orstcs.UUCP) for pointing this error out to me. For those of you that didn't see the first article: DEC has discovered a problem affecting ~9% of the J11 chips made before May 1,1984. I have (re)posted a large article to net.sources.bugs discussing the problem. The article contains diagnostics and the hotline number from DEC. -- Stephen C.
