I've come across a few old ICs and haven't
been able to find out much
 about them - lots of places on the 'net are willing to sell them but I
 couldn't find a data sheet - only one clue that they _might_ be dual
 op-amps. They are small cans (TO-??) with eight leads protruding from
 the bottom, marked SG 1458T with a 1976 date code. Any help identifying
 them would be appreciated. Kind of hoping they're really some sort of
 shift register ... 
Yes, it is a dual op amp, Silicon General 1458. Standard stuff, but
worth saving.
