starting address of the EPROM in the target system? Your offset is
relative to that.

move it, then burn a new EPROM. Much easier than sending back to a file
and editing it.

Thanks. I have among other projects been working to use a North* MDS
controller operate within an Altair system. I also have a working
Northstar Horizon system that runs N* and N* CP/M. On my Altair I am
using a 2SIO card. I have found indirect docs on how to personalize
N* DOS for the Altair 2SIO card, but so far I have not been able to
make it work. Any details of your version of N* DOS would be useful,
and/or a few representative disks.
If you were looking for a home for some of/all of the disks, I would
work with our club members to get CBBS running again.
