it doesn't look all that muc like a 5150 probably because it isn't one. Durn looks just like a 5170 to me. I have the 5150 version. Don't know if it's tempest tested or not. Figured it was simply a loosely mil-spec, ruggedized, industrialized version for certain environments. There was a "compatible" CGA monitor (Terry Yager used to have one).
Mine doesn't have a keyboard, so surely utilizing a vanilla k/b will render it "powerless". Or what have you. AAMOF, if anyone wants the thing, w/the rust that has accumulated due to being stored in a something less then sealed outdoor shed, it's their's for shipping. The power switch is also missing. I think the p/s is there though. You could strip it down and repaint it I guess :)
