Clearing out my late father's electronics pile, up for grabs is hundreds of CMOS logic DIP ICs.  There's a whole swag of different gates, registers, multiplexers, etc.

They're in anti-static tubes but can't guarantee they've always been handled accordingly.

If anyone is interested they're yours for free but I do ask that you collect them from Whitby, Porirua.  (I don't have the energy to pack and post.)
