Hi Vorticon, I have managed to get the disk images onto some disks that the P-System can read and they all seem to be working fine. In looking over the documentation, there is a Utilities manual that discusses some programs that I'm not finding on the "EDT/FLR", "COMPILER" or "ASM/LNK" disk images. Is there another disk with the utilities on them? I'm seeing utilities like "DECODE", "DFORMAT", "LIBRARY", "PATCH" and so forth.
