In a Discord discussion with Wayne Campbell, the topic of software registrations came up. Did you ever register any CoCo stuff?
Here is the one we sent out with our stuff…

The next time I go through my Sub-Etha Software archives, I am going to see if I can find any of these that folks actually sent in.

I’m pretty sure I registered Stylograph (Great Plains); I don’t remember much CoCo software coming with registration cards. I don’t think any of the Radio Shack games did.
