Those daughterboards were almost as rare as hen's teeth.  I have seen two, I 
think they are both still in my midden heap, but things need a going through 
and thinning down soon as it has been years since I last saw them and other 
CoCo goodies.  You should be able to use 8 of the common 64k by 1 bit chip 
in that machine, Or use 2 of the 64k by 4 that came out of a CoCo 3 upgrade.
