Issue: 80-Column Mode Not Working

Question: 80-Column Mode Not Working

Problem Description:

I'm trying to enable 80-column mode on the apple2e emulator, but I'm having trouble getting it to display correctly when using PR#3. The 40-column mode works fine, but when I switch to 80-column mode, the display does not render as expected. In essence, it appears as garbled 40-column text. PR#0 does successfully return it to a normal 40-column

Is there a setting I need to implement in a .js file to make it work correctly or is there something else I should be doing?

Thank you!

Thanks for the feedback. I need to implement an 80 column card. I will have a look at what would be involved at emulating one at slot 3.

I wonder if this other project might be of assistance, especially if you're otherwise starting from scratch. https://github.com/btb/80ColumnCard
