I can't find any info on that... try calling the local computer guy (every town has one!) He might be able to borg it together for you.

Look into some system info tools. There are many free ones out there that will give you the ID of various components in the system. Try a search for AIDA32. It's a good, free utility.

The only one I can think of from the top of my head is the MAXIM  ICM7211 / 7212  which has a function input "BCD or Binary" on its pin 4.\nSee data sheet http://pdfserv.maxim-ic.com/en/ds/ICM7211-ICM7212.pdf   and its Truth Table on page 10.

The IntelligentG list is pretty good, but note that no list is going to be complete.  There are just too many.  I doubt you will ever see C2B4H7(-) in a list.
