[Coco] 128K CoCo2

Wed Apr 22 08:11:38 EDT 2015

Kip, some cameras (cell phone, video camera or otherwise) have a zoom feature, so you stand away from the object you will be photographing and zoom in to get a close up. If you are lucky, some cameras actually have a macro feature. When you select that you can get the camera up close to the object. For macro shots don't use zoom (or use it very carefully). Salvador

Hi Joe,
I'll be happy to take some pictures for you.  I have is a cell phone,
but I have problems trying to take focused pictures.  I'll also try my video
camera that has still picture capability, but again close distances seem to be a
problem focus wise.  I'll do the best I can.  :)

Would you mind snapping a few pictures of it in your CoCo? I want to replicate

just looked at the article you mentioned below and my 128K upgrade is exactly
what the article describes.  I tried the POKE

interesting to say the least!

Just curious if anyone here has actually performed the upgrade and if 128K is
the practical limit before doing some massive

Don't recall ever seeing any software marketed for 128k.
