[Coco] Disto 2 Meg kit

[Bob Devries]

Sorry, Stephen,
You mentioned that you couldn't find the DISTO docs on the ftp site, so I 
sent you the link.

That said, you're right, it would appear to be different. The doc on the ftp 
site is just the installation manual. There is no schematic of the 2 Meg 
boards there at all, but given previous comments regarding Tony's habit of 
purposly giving out false data, I'm not sure I could trust them.
