Hi Mike! We made some changes to the third prototype to add the TMI circuitry and remove some of the redundant debugging hardware. You'll notice the board is using the DIP-64 version of the CPU so it is back to closer to your MMU design. The PCB is taking forever to clean up the trace routing although recently it is showing signs of improvement. Slowly though... Please keep up with the MMU design because there is going to be an S-100 68K CPU board eventually! Thanks and have a nice day! Andrew Lynch [snip] PS. Sorry I've been slacking on the 68K work, guys, I've been just up to my neck, it's getting closer to the front burner however. Mike Sharkey http://8bit.zapto.org
