Hi Chris Groessler and I have been working with the CPM-8000 images that we found on the unofficial CPM page, along with manuals and such found elsewhere. Last night, I was able to get the CPM-8000 prompt and execute both commands that I tried ( DIR and USER ). There are still some minor issues but things should be moving right along ( why can't programmers realize that initializing variables is an important part of any program? ). I want to give thanks to Hans, without the hardware manual he scanned, I wouldn't have been able to figure out the address decoder PROM in my Olivetti M20 and find out how to bring my machine up to 256K of RAM ( needed by CPM-8000 ). We still have some work to do ( building up the disk with all of the files ) but it looks like a down hill trip from here. Later Dwight
