Well, from my limited knowledge of Vector systems, AFAIK the multi-user systems did actually use a standard 48K CP/M and not MP/M; each terminal loaded it into its own memory card and the supervisor ROM looked after time-slicing among the cards. Not sure what MDM7 has to do with the Flashwriter, which is essentially just a video display and parallel keyboard interface. But the question still remains whether the FDD is soft or hard sectored; it does indeed look like a Tandon and not the usual Micropolis and if the model number can't be relied on, how could one tell (other than by trial & error)? mike ------------Original Message--------------------------------------------------------- Date: Wed, 23 Nov 2005 18:24:43 -0800 From: "Chuck Guzis" <cclist at sydex.com> Subject: Re: CP/M 2 - what's its legal status?

FWIW, if you're wondering about the Flashwriter cards, there's a MDM7 overlay for them wandering around on the web. Cheers, Chuck
