Thanks for your help on this Mark, it's making more sense now. I have the
AH5010,'11,'12 data sheet but wasn't sure if it was the same thing or a
later similar device.

I'm still a little confused on the C's. The 1995 AH50xx data sheet shows
the AH5010 and AH5012 being 5V logic, and the AH5011 being 15V logic (the
AH5009 is no longer shown but was presumably 15V logic based on the missing
table entry). Now, based on the 1980 info, AH5009=AM9709 and
AH5011=AM9711, so this *implies* the AM9709 and AM9711 are also CMOS making
the C versions AM97C09 and AM97C11 superfluous, which seems odd.
