Seems every time someone applies that to hardware with a wider compute path, other complexity creeps in.
Would be interesting to make a 32 bit Apple 2 style computer. Include a ROM for a means to boot, and leave everything else simple, with some nice slots. Could be a great development / learning machine.

- ddingus 5y agoYes, but perhaps aimed more at retro computing. I have a couple of those. The HYDRA was a lot of fun.
- cmrdporcupine 5y agoI've "built" such machines in FPGA; PicoRV32 core, hand made display processor, a bit of RAM, and a couple UARTs. It was fun and not that hard for me, a newbie to FPGA. One of the bigger challenges is integrating peripherals. I got bogged down trying to do SD Card interfacing. There are off the shelf bits of IP from Xilinx, etc. you can use to do this, but that sort of defeats the purpose of the exercise. I think modern machines started their slide into mind boggling complexity when bus speed and CPU speed outstripped RAM speed. So much complexity and unpredictability is in the all the infrastructure built around cache. Something like an Amiga or Atari ST was still not hard to understand all/most of, despite being 16/32 bits.
- ddingus 5y agoThose kinds of things can be done with the CPU, Apple 2 style. Map some I/O to a few addresses and service the SD card with a small routine.
