Sliced off a bit...>>>>>>>>>>>>>>>>>.
What you have is a NS* horizon chassis, CPU and ram with a DJ floppy
controller. This was fairly common upgrade for more floppy space and
more accessable format.
Its likely running CP/M and the DJ card has a boot rom on it.
The NS* ZPB (Z80 card) rarely if ever had the rom section populated
so this is normal.
You have a 64k ram card that sounds like 48k is enabled.
Finding a boot disk is troublesome. While you can find one for the DJ
controller the serial (console) IO may be or may not be set up for
NS*. The result is it would boot but communication with console is
unlikely. Since there is no resident software other than boot you
will need another system that can create a disk with the needed IO.
This problem plagued many as it's chicken and egg.
