I think you had mentioned something about arrow keys being different in the current implementation. Which control codes are you referring to? The whole set of Model 100 escapes? Which is fine... that's one way to go and it can be implemented exactly. It just isn't VT100. The other issue is encoding and fonts. HTERM does this mapping on the Model T side, which makes it compatible with any shell/terminal. But you could also do a mapping to Unicode on the terminal side. Then you could use off-the-shelf fonts. Another way to go would be to render the display completely yourself with graphics based on the Model 102 character set. Then you could get very high fidelity. As to VT, it's just a terminal, so you don't need 99% of what VT does. And what VT does do that you need, like rendering the display, has to pass through the Model T ROM and 8085 emulation. And it's limited to 40x8. Seems like it creates more problems than it solves. Just displaying character bitmaps to the screen is a simpler task. -- John.
