I feel like the CX16 lost its way about a week after the project started and it suddenly became an expensive FPGA-based blob. But at the same time, I'm not sure what other option there is for a project like that.
I always got the impression that David sort of got railroaded by the other members of the team that wanted to keep adding features and MOAR POWAH, and didn't have a huge amount of choice because those features quickly scoped out of his own areas of knowledge.
It's incredible how influential Ben Eater's breadboard computer series has been in hobby electronics. I've been similarly inspired to try to design my own "retro" CPU.
I desperately want something as easy to plug into things as the 6502, but with jussst a little more capability - few more registers, hardware division, that sort of thing. It's a really daunting task.
I always end up coming back to just use an MCU and be done with it, and then I hit the How To Generate Graphics problem.
> These effects consist of oxidative stress, DNA damage, organ dysfunction, metabolic disorder, immune response, neurotoxicity, as well as reproductive and developmental toxicity. In addition, the epidemiological evidence suggests that a variety of chronic diseases may be related to microplastics exposure.
