Does anyone of you have a clue (i.e. timing, supply voltage limits, complete pinout) about the following chips:
MC 660 L 4-NAND MC 671 L tripple 3-NAND MC 672 L quad 2-NAND MC 680 L hex INVERTER These are in a piece of control electronics dating back to 1972-76. They seem to be straight-forward logic chips running from a 15V supply (CMOS? hardly I believe...). I am looking for possible drop-in replacements, otherwise I would have to re-do the whole thing with its 30+ chips on three PCBs in a more modern technology... I don't even know where to start to look for the malfunction...
