I was about to recommend the Parallax Propeller (the first one that's available in DIP format), but arguably, that one is way more complex to program for (and also significantly more powerful, and at that point you might as well look into an ESP32 and that is "just use an MCU" :))
And yeah, video output is a significant issue because of the required bandwidth for digital outputs (unless you're okay with composite or VGA outputs, I guess they can still be done with readily available chips?). The recent Commander X16 settled for an FPGA for this.
