Did you guys ever find a source for any TIL306's?

Hello Joe.
I ran across your message at
http://www.classiccmp.org/pipermail/cctech/2003-January/007306.html
about the TIL306. Did you or Toth ever find any TIL306's? I am also looking
for some (8 of them to be exact) and like you and Toth have been able to find
several TIL311's but no TIL306's.

Thank you.

Jim Pruitt

     I need the counter function but I'd like a copy of the PDF anyway.

   Same here. I squirreled away a lot of parts over the years but found that
many of them were damaged due to the foam. Fortunately I've get some pretty
good scrap sources and I've been finding lots of military grade cards with
socketed ICs in the last couple of years so I've been picking them up and
pulling the ICs and storing them in parts cabinets. I've amassed a huge stock
in just the last year. I was also lucky last year and picked up a good number
of parts cabinets that have all the drawers made out of anti-static material.
I had been keeping the parts in anti-static foam for AS protestion but now I
don't have to.

   I have a fair number of 308 and 311 displays that I've pulled from cards
and the local surplus place has plenty of them but the 306/307s seem to be
scarce.
