Hi James and Max! I am very pleased to hear that development is pressing for a MultiOS Z80 Multicomp! I delighted to hear about getting the MMU files as well. I'm trying to figure out how to get the CPM3ON2 files I found running on my Z80 Multicomp. Not much documentation came with it though. I'm especially glad to hear about the new PCB design! Keep up the most excellent work you and Max have been doing! I just might learn Z80 code yet! As you know up to now I've been exclusively a Motorola Man! Anyhow, take care my friends!

The MMU and MP/M has been me and Max exchanging mostly private emails. I wrote the MMU and he wrote the MP/M code. It isn't finished yet though - he is working on handling interrupts from multiple sources and I'm deep inside the theory of Moore State Machines in vhdl http://www.altera.com/support/examples/vhdl/vhd-state-machine.html I'll post the 4K MMU code when I get home. Max has written a full page step-by-step instruction on getting multiple operating systems working via one SD card but he sent me that as a private email so I should defer to him regarding posting the code (or sending it directly to you). We are thinking about a new board - more RS232 ports, maybe dual SD cards, all the connectors along one side so it fits better in a box.
