Where did you find $18 sockets?  That wouldn't be so bad.  (they'd =20
have to be sockets, not adapter boards that you solder to!)  (Ah, I =20
see.  From Silego themselves!  Just order both development kits and a =20
spare socket in each size.  Should be interesting.

Also, it appears that these are actually RAM-based logic, with the OTP =20
backing up the RAM.  Using their (cheap) emulation/programming board, =20
you can apparently load up the RAM as many times as you want, do some =20
testing via their tools and external connections, and have a jolly old =20
time trying things out

   I wonder if it's possible to put a small battery or large cap on a =20
DIP adaptor board, and have a short-term part that can be moved from =20
one place to another?  An interesting project.

And they have a Mac version of their developement software.  how could =20
I resist!
