lipsher@eecs.ucdavis.edu (Jonathan Lipsher) tells me:
If I'm understanding the circuit correctly, it appears that the control
signals which come out of the '139s need to be inverted before they can
trigger the '374s. This could easily be done with either a 74HC00 or
74LS00 because of the HCT componentry in the rest in the rest of the
circuit, by making inverters out of the NAND gates.
I haven't looked into this. Anyone else care to confirm it?
