Or if a picture would help (it's quite large):

Hi,
And how about a guess at a 711 dual-comparator for the last one. Cheers - Joe
Maybe, but that seems to be the date code. At least, the others have date codes of 83/84 (except for the one with a '78 date code) and you can be sure of those dates since the IC numbers are very clear. That number with the 711 has a bit that has an 83 or 84 in it, which matches the vintage of the other ICs.
