Slashdot | Bringing Back the PDP8 relates the efforts of Andrew Grillet and his attempt to make a PDP8 clone using FPGA chips.
I’m virtually certain that this is a hideous waste of time, but it is kind of a cool project, and given that I spent a couple of weeks writing a PDP-1 emulator so I could play SpaceWar!, I don’t hink I’m really one to talk. He’s using a Xilinx Spartan II FPGA for implementation. Pretty neat, but I can’t help think that a PIC or Atmel microcontroller would be a better choice these days.
