"Again IIRC, the Tandy 200 can’t do that because the screen memory is stored in the LCD driver chips, right?"
No, that is incorrect. True, the *pixel image* is not stored in RAM, just in the lcd hardware. But there are two RAM areas where the ASCII characters are maintained, LCD and ALTLCD (for restoring after switching control modes in TELCOM). https://bitchin100.com/wiki/index.php?title=Model_T_Cross_Map_RAM_Variables So I think you should be good for your port. No faking needed. -- John.
