You "get it into a NorthStar", by already booting the NorthStar to CP/M, and using PIP.

NO matter what first you have to boot the horizon and if you lack prepared media its a hard stop. 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.
Thanks That answered several questions that I was wondering about! -- Grumpy Ol' Fred ci...@xenosoft.com
