I'm sure Bill is looking for someone with the image, or the chip masters. I looked @ the listing provided, it's assembled for org 0x00. There's a different org for CPM.  So you can't use the CPM binary in rom unless you put a rom at 0 to jump to the CPM binary, and I'm guessing it has conditional assembly for the serial drivers. http://www.s100computers.com/Hardware%20Folder/IMSAI/PROM/PROM-4.htm Will be interesting to archive if someone comes up with it.  Wonder if anyone with the basics for the clone boards may have a basic which could be used that runs on such as the Altair or Imsai clone? I know the Altair clone has a number of alternative boot images you can select from, could swear one is Basic, but don't have the documents handy here. thanks Jim
