CA 3019, MC 796?

[jorgen.bergfors at idg.se]

I looked through the schematics for the Moog modular, and found a couple of ICs 
that I haven't seen before. Anyone know if they are available or if there are 
equivalents/replacements?

CA3019: contains six diodes.

MC 719, 778, 793, 796. These are logic chips. TTL, DTL, RTL? Probably some 
precursor to the 74xx series. Are there 74xx equivalents?
