When I have some time, I plan to look though the disk image and figure

Since the HDOS version had no problems, your transfer was probably fine.

Wow, thanks for taking the extra effort to make the image, I had
assumed you just used the H89trans program. I have a couple of things
I plan to try tonight to see if I can get it working but at least I
have a working version now.

Has anyone else on the list created a disk from that image? Are you
able to run the CP/M version of space odyssey?

Thanks,
