[Coco] how to find out BASIC version?

[Torsten Dittel]

How can I get the version number of the Color BASIC if an Extended Color
BASIC is installed? There was an EXEC to get the startup message or some
PEEKs but I don't remember that. I'm trying to make an inventory of my
CoCo collection and thought it would be nice to have that info beside
the Cat.-No. I also have a disk controller without label, how can I find
out which one it is?

Regards,
Torsten
