I located a supply of 74AC175PC for $2 USD at qty 100. I still need 2 of
them to finish off all of my PICTIC II's (I have 3 completed). Are there
still some available from people willing to part with some? or is there
enough interest in that I could distribute enough of them to list members
at cost to make an order worth while?
