@rprouse @RenewedRebecca @thomasfuchs I loved the ti-99 4A too! I wrote a couple of games when I was in high school which made it into 99 er mag and then wrote Night Mission which was distributed as open source by Millers Graphics along with a book that Craig Miller wrote about how to write video games. The key was sprites as well as the 3 voice sound generator. Such an awesome computer.
