The 7109 is an adc, of the dual-slope integrating variety more or less like
the panel meter IC's Intersil developed and everyone else copied. I think
www.maxim-ic.com is the place to look for the functions on this board. I'll
let you guess what the DAC800 is. (chuckle) If it's working, it's probably
a keeper. Look for any additional identifiers and then hit the web with a
search for that.
