[net.micro.trs-80] CoCo memory upgrade

jnk@drutx.UUCP (KelleyJN) (05/09/86)

    My father has a Color Computer and I finally talked him into
a 64k memory upgrade, however after installing the new chips and
putting in a strap at location "W1" on the mother board the unit
only recognizes 32k.  My question is do I have the strap in the
wrong location and if so what is the correct location or do I 
have a chip failure.  The computer works fine up to 32k.  Thanks
in advance for any help.

I own a coco as well, and if the machine tells you that you have
32K available space from basic, then the upgrade has been performed
fine.  To find out where that other 32K went get the technical ref
manual and look at the memory map layouts./..
