If you are a fan of old computer systems, then you have already noticed that the devices are becoming scarcer and more expensive. For an original 80486, MSX, Amiga, Atari ST or Amstrad you have to dig deep into your pockets… if you come across one at all. For many, there is no other option than to work with emulators or virtual machines. Unfortunately, this does not always give the desired result. Fortunately, there is an alternative: build it yourself with a special chip and separate parts.
