Advantages of Minimig with ethernet:

  • No need to use flashmemories
  • Faster
  • Can be used online
  • Faster development cycle (edit - test - crash ..)
  • Handle decompression of disc images

Relativly simple. Needs only an ethernet PHY in essence. Thoe only 4 user i/o is free = problem.

A cheapskate version is to use on pin per direction without protective magnetics for 10Base-T networking. Uses easy manchester encoding.

An I/O expansion could otherwise be done with an external fpga-2 that communicates with the first one via a highspeed bus.
