[Coco] CoCo 2 16k.. Upgrade or no?

[Chad H]

Thanks.  I also have the "All Ram Mode" BASIC program on a .DSK image if
needed.

Type in PCLEAR 0 and see if the memory increases.   Remember, a 16K  
computer has 16K of actual RAM (locations 0 - 16383).  A lot of that is used
up by BASIC (and the graphics screens).  For 64K machines, normally only 32K
is available (locations 0-32767).  There is a way to get it into 64K mode
(an all-RAM machine) where you can go poke up BASIC (lots of fun).  I've
actually posted the program that does that  
to this list, and if I can find my notebook, I'll do it again.   
Basically, it changes the "map type" back and forth while copying over the
contents of BASIC.  Once again, BASIC, cartridge memory, I/O memory, etc
take up space, so you'll get no where near the 65536 bytes implied by "64K."
