There are a few adapters over on that "auction" site. Do a search on 14 pin smd to 14 pin dip.

How do you use a 14 pin SMD IC? I could try to connect it with flying leads but I'd like something better. Is there some kind of socket for these devices? Or a generic board to receive such things?

AS (advanced schottky) and FAST (fast advanced schottky TTL) were the best for me. Modern inexpensive discrete logic however can do a much better these days. One interesting thing I learned is that the dual 4-input NAND pinout overlaps the quad 2-input NAND pinout so in a properly designed layout where only 2 gates are used, either part can be used.
