North Star Horizon Help

< Ok, I have a few minutes now to play around with the N* Horizon < I've been fixing up. I've tried to power it up and it seems to hit the < disk drive and then nothing. I've plugged some spare terminals into < the port marked "Video Terminal Port" and played with baud rates < and other comm settings but get nothing on any of my terminals. There is no resident monitor or software other than a disk boot in a standard horizon. It will not say anything to a terminal untill it boots (assuming the booted code has something to say). If the boot fails likley the only signals you get is disk activity or the lack of it. Make sure you have at least 32k of ram starting at 0000 for CPM or 16k starting at 2000h for NSdos. < Also tried straight through and flipped comm cables. Can < someone give me some info on these and maybe walk me through < getting it set up and running so I can check and see if I've missed < something? Oh, I'm trying both N*DOS 5.2 and N* CP/M 2.2. Are they personalized for the machine and are all the port headers don on the mother board set up correctly? Are the media the correct density for the controller in use? I have and still run one. it occurs to me, if you have DOCS for it the setup and checkout procedure is in there. Allison
