I think I just about make out the T for 74hct02 in the photo posted earlier but maybe you could confirm thats what you used.

For the NENIN pull down on your MK14, is that 4.7 k. I think thats what you had on your schematic for the issue VI. Just wondering if you instead used 1k or lower, which combined with the 470 on the ortonview might stop the pic output from pulling up high enough.
