Yes the Master Z80 monitor talks to the Propeller I/O board fine. That board is normally configured for I/O ports 0 and 1H. If you have it otherwise you need to modify the code. Also be sure the status bit jumpers are correct. Again, I use the configuration on the S100Computers web site. Good luck John From: n8vem...@googlegroups.com [mailto:n8vem...@googlegroups.com] I am in the process of building the latest S100 Z80 Version 2 board. I have a question. First, I want to use the Z80 board with the prop I/O board. Is the Z80 Master ROM setup for this? On the S100Computers site the latest ROM is version 5.04 which has two 4K sections but in the writeup I didn't see any mention of support for the propeller I/O board. Any help would be great.
