Hi Group, Well, the moment has come for me to stand up and admit I'm an idiot!
This has come after a long search and struggle to find out why CP/M 2.2 would not save files correctly. Apparently in CP/M 2.2, they number the sectors from 0. While, iirc, in CP/M 1.4 it started at 1. I spent hours testing my disk read/write routines and could not find faults. I even thought my CP/M image got corrupt, and Rich Cini was very kind to send me another image. I was hoping the files where different, but that wasn't the problem either. The whole fix, just really required me to remove a simple "Decrement Sector" instruction because I thought CP/M used 1 as it's starting sector, where I needed 0. Sigh... ok, problem solved.... New firmware file and Disk file images (with CP/M standard files uploaded) on the wiki site at: http://n8vem-sbc.pbworks.com/w/file/88759892/FIRMWARE%20and%20CPM%20v-disk%20image%20AIR-V12.zip Cheers!
