Haverkamp) Newsgroups: comp.sys.apple2 Subject: Re: MS-DOS Message-ID: Date: 30 Jan 91 06:39:01 GMT References: <7240@crash.cts.com>, <11618@darkstar.ucsc.edu> Organization: Carnegie Mellon, Pittsburgh, PA Lines: 17 In-Reply-To: <11618@darkstar.ucsc.edu> In regards to the response that the PCT only uses a pseduo MSDOS on a GS 3.5, it should be mentioned that this only correct under certain conditions. When the GS 3.5" drive is connected directly to the floppy cable from the PCT, it actually will read and write "real" MSDOS. Well, real enough that I could write programs on my GS at home and take them to a friends MSDOS machine, stick them in, and operate from them. By the same token, it will also read 3.5" disks formatted and operated originally in a true MSDOS machine. When, however, the GS 3.5" drive is connected to the Smartport, they are actually written to in a special format, that can only be read in by the PCT. This is the same thing that happens to 5.25" drives connected to the Smartport. Greg Haverkamp GH1W@andrew.cmu.edu
