[sdiy] Intro and basic IC compatibility question

[James Patchell]

The 74C14 "might" work...let me go get my Midi->CV docs...if this is 
IC6...I would say there is about a 99% chance it will not work...the usage 
I am not sure about is IC6D where it feeds the 74HC373...(provides the 
strobe to latch the data bus for the DAC).  The 74C14 is a bit slower than 
the 74HC04, and I am not sure if you will violate the setup and hold times 
for the data bus...I think you would be best off getting the correct 
part.  If you were my neighbor, I would trade you a cup of sugar for one (I 
assume you do not live in Santa Barbara)...
