The other video is of a program called DRAC that I worked on recently. James Host the admin of the MC-10 Facebook group challenged folks to come up with some seasonal programs. So I whipped up something quickly over an evening. Just stole some ASCII graphics of Dracula and some lips with fangs from the Net. Plot them using SET/RESET. Little graphic work with my SKETCH program for some big text and graphics for a few wee animated bats and Bob's your uncle.
I decided to put them on my real MC-10 and then put them on a loop using the MCX-SD. Just have each program RUN the other. MCX BASIC lets you use a filename with RUN so you can easily chain programs together. Who says BASIC isn't useful anymore!
