Thanks for the reply. The only hurting I was concerned about was the hole
I'd have to cut to pull the screw out. I know I'm probably being overly
worried about nothing, but it should be easy to find an old cartridge with
the label already gone, right?

So in short, Basic can only use 32k max for code and data, right? If I
understand correctly, the ROM is not copied to RAM by default, which
leads me to thing that the upper 32k of RAM is not being used by Basic.
This would be on a CoCo 1/2 if that makes a difference.

I just recently found the site, and it looks as good as any I've found so
far, but it looks like it's mostly stuff for the CoCo3, which I don't
have. Even a place to ftp/download software would be useful. Thanks.
