These kits do include generating the video: https://gigatron.io/ https://gigatron.io/ "... low resolution video had come within reach of our design, without adding chips. This was possible by taking the unconventional step of bit-banging video signals from software, instead of designing a standard video generation circuit. ..." https://basicengine.org/ https://basicengine.org/ "The VS23S010D-L ... is a static RAM chip ...
