OS-9 Level1 v2.0 includes provisions for 80 column screens. I suspect
you don't need to do the work implied in your message.
V2 includes a /term for 80 columns and a CO80 driver. Include these in a
boot file using Config and my guess is that the system will work with
the WordpakII without further changes. You switch between the two
screens (32, 80) with Tmode.
The V2 supplement manual refers frequently to an 80 column card but does
not mention the Wordpak or any other card by name.
