TRS-80 Model II

I've searched the world web over ,but never did I find...... There seems to be a lot of info on Mods. 1,3,100,Coco etc. but nada on this beast. Any sites I might have missed ? Merch , Cord ? What I have is a TRS Model II with 1 internal 8' fdd and 1 external fdd , 3 humungous 5Meg hdd ( about the size of a large XT) , K-B , TRS model 7 modem , and a box of 8" disks with CP/M 2.2 , TRSOS, Scripsit and a bunch of other prgms. When I boot up with or without an OS disk I get a "boot error ht' msg. The dd spins up and sounds like its loading. Could it have been set up to boot off one of the hard drives ? I'm really a novice with TRS-80s but have Coco 1 and 2 in my collection and a Scriptsit cart. Is there something I'm not doing ? ciao larry lwalkerN0spaM(a)interlog.com
