LM324.
The horror!
National used to make a combo LM358/LM393 amp/comparator. (LM611 and
614 maybe?)
IIRC JT said that the two were the same silicon with different
metallization.
But for slow stuff that has to be very cheap, using a section of a 324
as a comparator works fine.

One thing about the classic National LM324 is that if you rail any
section, it wrecks the shared bias supplies for the other sections. So
one comparator switching *really* messes up whatever the other three
amps are doing.
I think some peoples' later versions didn't do that.
The 324 is my favourite opamp ever. You get so much for so little.
