[Coco] Moving 6809 to socket

[Zippster]

And a ZIF socket may have a significantly larger footprint too.

It might not fit.

I would go with a machined socket, because I perceive them to be
higher quality, though there are definitely people who prefer dual-wipe
sockets.  A machined socket is also easier to remove (destructively)
in my opinion, should the need ever arise.

Why would you need to swap between 6809 and 6309 CPUs?

AFAIK the only way in which the 6309 wouldn’t be compatible with
6809 code would be if you were using illegal opcodes that would
trigger the 6309’s error trapping (active in both native and 6809 emulation
modes).
