[Coco] superpet

[Boisy G. Pitre]

Willard,

You might find this link to be of interest:

http://www.commodore.ca/gallery/magazines/misc/SuperPET_OS_9_TPUG_Feb_1985.pdf

I've emailed the Toronto Pet User Group at info at tpug.ca to see if  
anyone has a copy of OS-9 for the SuperPet, but never got a response.

Regards,
Boisy G. Pitre
