I just realized I have a 9995-based Tomy Tutor in my closet. Now that I know about this project, I'll have to dig it out. FWIW, for the two years I lived in Richardson, TX, I drove by TI mainside every day to get to work. I eventually remembered how much fun 9900 assembly was and got the vanity plate BLWP [Branch and Load Workspace Pointer], one of the most unique 9900 instructions.
