Bootstrapping a Horizon if you don't have a

it can be done - the main issue with a Horizon is "how to I get the code into
the system" - because there is no front panel or ROM monitor. Fortunately
there is a 1K ROM socket on the NorthStar CPU card. I can provide a little
(500 byte) monitor which will provide basic read/write memory commands, and
the tool mentioned above can be configured to "type" data into this monitor
as well - I have pre-configured in-ram images of both single and double
density NorthStar DOS with my client which can be transferred into the system
and launched using this little ROM monitor. Then you use the PC "NST" tool
to transfer a boot disk image to physical media.
Dave,
Where can I get ahold of the image for that ROM monitor? I have a Horizon
here that came with 9 boxes of hard-sectored diskettes. Unfortunately all
of them are blank :-). Any tips on bootstrapping my way into a functional
system would be greatly appreciated.
