<> NS* were setup with 16-62k of ram. There were three common OSs run on <> them NS*dos(nothing like PC dos), CP/M-80, there was also UCSD pascal <> P-system. I believe NS*dos reached at least V5.4. They didn't not use <> a monitor or keyboard as a terminal was commonly used. < <While agreeing 100% with what you say, is there any reason why you <couldn't put one of the many S100 video boards into an NS* and plug a <monitor into that You'd probably still need a terminal for text I/O, but <I can't see why you can't have a separate graphics display as well. Typical NS* was set up that way. That was not to say they were configured with an assortment of third party cards. Mine never had a NS* ram card VDM-1 until I got an H19 a few weeks later. No doubt over time most any combination of cards made it in to a NS* crate. It was a good crate for upgrading and mods. Allison
