[Coco] Space Invaders - Translated from Intel 8080 to Motorola 6809 for the CoCo 3

[Paulo Garcia]

Hi Glen

First of all, this is really good stuff. The article is very interesting!

I looked for the file but I think it is too soon to have it available for
download. I wonder if you would send me the ZIP file so I can write a quick
post on Vintage is The New Old about your article.

Cheers


Paulo Garcia
