I try to limit my gizmos to thru hole packages to
make them easier for
the
hobbyist to assemble, and there just aren't any CPLDs available in thru
hole
packages that also have anywhere near enough logic to implement a whole
CRTC.
Yes, they are! :o)
The chip may not be TH, but the sockets are :) I have thru-hole sockets
for thing up to PLCC-84. Why not use that?
