Hi, My find of the day was a "Northstar Advantage" and as per my normal luck with CP/M systems no OS. Still it seems to power on OK. I've got a few questions on it. First and formost would be where can I get an OS (would the Osbourne version of CP/M boot it)? Is there a "Monitor ROM" that I can drop the machine into? I see from the list of computers on the mailing lists web site, it's got a Z80 and a i80186 processors in it, OK that's nice, what does that mean to me? Also are there any good info resources for the "Northstar Advantage"? The one I've got has a 1" x 6" strip of metal with two threaded posts near the top sticking out (great for messing up arms), it's been stuck to the side of the case with that thin sticky foam, is this stock, or an add on? Any ideas what on earth it's for? I'm thinking a copy stand. Pardon my probable stupidity when it comes to CP/M systems, I think I'm up to four of them now, but only the Osbourne has disks and it won't boot, I think it's got a bad A: drive, because the disks boot a friends Osbourne.
