It used to be you could go to Radio Shack and pick

a 'brand new' s100 SIO card that is just missing the 14 logic
chips to go in the sockets, but I am not finding a convenient
source for them.
Anyone know where I can go to find them in very small quantities?
DigiKey or Unicorn Electronics.
Both want $25 on the order or a handling fee applies.
If the chips are rather ordinary, BG Micro might carry them. I
don't recall a handling fee, but their entry-level shipping is
a few bucks, minumum (I think they use a flat-rate Priority Mail
box for small orders). I tend to place two or three orders per
year from them, so I've never felt like the shipping was a huge
chunk of the order, but 14 TTL chips for well under $1 each,
with $8 flat-rate shipping makes each chip a bit pricey.
You might consider batching projects and getting the parts for
two or three at once, if the cost-per-part seems high.
