[Coco] Replacing Dynamic RAM with Static RAM

[Steve Bjork]

Please note that CoCo3.com been having a bit of a problem with hackers 
and all uploaded pixs are gone.

This is not the first time that post or uploads have been lost at 
CoCo3.  About a year ago, CoCo3 lost years of posts by me and other 
users on the site.

Also, a number of long time "free" hosting site have killed off their 
service (like AOL) and taken a number of old time CoCo sites with them.

A good rule on the net these days is post on your own site if you want 
make sure it stays there.
