lol! That's very nice!
How is the 81 so fast?
And faster than a 83. Does the IS>( command do so much difference?
I would like to compare the 81 and 83 with the same code.
I did, before doing that video. Wrote the exact same code as on the TI-81 and it ran even slower than with For(. To me, the TI-81 probably has much faster home screen scrolling routines, by far, because on the TI-83+ if I just do For(Z,1,999:Output(1,1,Z:End, it goes faster than the TI-81 code. Also, when I ported Illusiat 81 to the other models, I had to insert some slowdowns everywhere so it runs at same speed. Basically, the TI-81 may be 3 times slower than a 83+, but the Disp command seems considerably faster than on every other calc. (btw the reason why I used different code on the 81 is due to the lack of For(/While/Repeat commands)
