Hello Wayne,
My mistake, I was copying IDEUTIL to RAM (using AMON) and then trying to run it like that. When I run it from CP/M directly it works fine and I'm able to read data from the disk. I'm wondering how I can copy the data on the disk to RAM and run it from RAM. I don't see an option like that in the IDEUTIL menu. I would like to burn a simple program like that into ROM so that, when the computer is powered on, it executes the ROM program and loads CP/M from disk. I was getting close to having it do that but ran into issues where bytes were being skipped when it was being copied to RAM.
