The 6809 is soldered.  The GIME chip seems to be the only one socketed in my
CoCo3 whereas nearly every chip in my "D" board CoCo 1 is.  I have already
looked at every chip in the CoCo 1 some months ago when I was studying the
prospect of upgrading it to 64K and adding Extended BASIC if I can get a 24-pin
ECB chip.  But not one chip in that CoCo1 is labeled as a 6809 or anything
close thereto.  Even if I had found a 6809 in there it would only be a
temporary solution since I doubt it could tolerate 2 MHz operation for long.  I
never tried to run the CoCo1 in 2MHz mode so I don't know if it even can.  The
upgrade I am considering for the CoCo1 which Marty Goodman urges me to not try
seems to me to be no more difficult than replacing the 6809 in the CoCo3.  I am
certainly more confident in my potential for succesfully doing it than with
replacing the 6809.  I have already found a BG Micro ad in Computer Shopper
which I got when I began looking for something to replace my DuMP-107.  That's
also where I will try to get some 4164's to upgrade the CoCo1.  It's just the
ECB chip that's a big problem.
