I beg to differ Jeff. While SID 97-3G works for the job in question this bulletin
no longer exists. It was one of 20+ bulletins that were incorporated into the M-0 manual. Any updates to these procedures will end up in chapter 6 of the M-0 manual.

Unfortunately this manual needs to be purchased. I don't see any differences for the IO-240 from SID97-3G, go ahead and use this document.
