You can only truly appreciate the Z80 when you start using the Repetitive Copy and Compare instructions.? With a single instruction, you can move a block of 64K as fast as the memory read/write cycles will permit.? Of course, that's the whole memory map and while that might be a useful thing (say your hardware can bank switch between reads and writes?)? it's more likely to do smaller chunks of data.? The speed increase to move blocks of data like this is really significant!
Are you reading any books on the Zed-80?

Good luck on your Z80MC build.? The "zed 80" was quite a successful processor.?
Hi Josh, Thank you so much for approving me. Yea, I did not really do enough with that processor years ago (so much changed afterwards as I am sure you all know) but I did see how many systems were created by it and did read a small bit about its architecture. A truly awesome micro. It will be so much fun to now get back into it. See you online!
