[Coco] Re: [Color Computer] Xpad an coco 1 16K

[Pedro F. Giffuni]

Hello;

I saw on the instructions that came with the memory upgrade (quite 
some years ago) and there were some changes required to update 
memory. There might be some resistor associated to Extended Basic 
that is giving you problems.
The big problem is that Radio Shack made different boards and all 
have different instructions on how to upgrade them, so you cannot 
compare two different boards.

Hmm.. the X-Pad... it's not really worth it, IMHO. I felt mine was 
too slow so I wrote OS-9 Pascal code to attempt to give it some use: 
I had to learn variant records to do the equivalent of Basic's peek 
and poke. At the end, even compiled code was not fast enough to drive 
it well. The Coco is a great machine to learn assembly though ;-).

Hope you find some upgrade instructions somewhere :(.

    Pedro.
