I believe that Mike Douglas has a utility program that you can get into a Northstar
Horizon, and then it can receive a .DSK image sent from the terminal and it will write the
disk for you in the Horizon.
It?s called PCtoFlop and I think he has it in his archive here:

Good luck!

I was thinking someone has already done this. If no, as you say, it is not an impossible
task.
The TSS/B is suppose to be their scientific package. It at least has BASIC in it. I have
another disk marked CP/M in the same box. I should be able to put something together under
CP/M.
It is a North Star Horizon. There seems to be some images out there so I don't know
how they are being captured.

You "get it into a NorthStar", by already booting the NorthStar to
CP/M, and using PIP.
It looks like an excellent way to handle more images, including N*-DOS,
AFTER you have CP/M working.

Mike Douglass solved it by putting an Eprom on the ZPB-A as there is a
spot for a 2708 1K part.
He made up a header to use more common signal voltage parts like
2716/2732 and so on.
With a machine language monitor that allows loading bytes to memory the
process is then easy.
Me I cheated and used a spare 64K memory board that used 2kx8 parts and
put an eprom (2716) in
the F000H space.? Change the CPU boot address jumpers from E800/E900 to
F000h and now
you can talk to it via serial port.
The PCput and PCget are handy and no so big to hand insert.

Thanks
That answered several questions that I was wondering about!
