There is another solution - call Workman and Associates in Pasadena, Ca. at 818-791-7979 (BBS: 791-1013) and order BDS from them. One of their services is disk format conversion from (and to) over 350 different formats, including 8", 5 1/4", 3 1/2", CP/M (-80, -86, -68k), MS/PC-DOS, UNIX, Atari, etc, etc, etc. I just got off the phone with Barry Workman, and he has no problem with supplying a copy of the BDS with a second set of North Star 10 sector floppies - in fact he has the media in stock. Let me know if this helps. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #Include disclaimer.standard #Include quote.cute The opinions above probably do not even come close to those of my employer(s).
