What kind/brand/type of diskettes does one recommend for the DEC rainbow? I've casually tried a bunch of diskettes and have had no luck unless they are original DEC diskettes made for the rainbow, or were already working with the rainbow. Again, I haven't given this problem enough attention to warrant true concern. I just want to save a 1/2 hour shuffling different types of diskettes until I get it right. I'd like to know about cheap ones because I often use my rainbow to do dangerous system tinkering and I'd like to have lots of backup copies of the hard drive. I know I've tried DS/HD and DD/DD. Maybe the ones I tried were garbage anyways :-) James +----------------------------------------------------------------------------+ + James Peregrino | JPEREGRINO@HBSSTG.HARVARD.EDU + + Programmer/Analyst | PEREGRIN@STIG.HARVARD.EDU + + Science & Technology Interest Group | JPEREGRINO@HBS.HBS.HARVARD.EDU + + Harvard Business School | PEREGRIN@HULAW1.BITNET + + Boston, MA 02163 +-----------------------------------+ + Voice: (617)495-6307 | My opinions are only my own and + + FAX: (617)495-0351 | never H.B.S's. + +----------------------------------------------------------------------------+

The Rainbow uses a DEC disk called an RX-50K, I think. The RX-50K is supplied with a strange, low-level format already applied to it. You can create this format on any HD and most DD disks if you have some of the support programs for CCPM-86. It has been a few years since I had a 'bow of my own to work on, so I don't remember exactly how to do it. -Chris Petersen Vanderbilt University Computer Center Petersen@vuctrvax.bitnet Petersen@ctrvax.Vanderbilt.Edu P.S. I may have a Rainbow again soon! Hurrah!

I can make any disk into an RX-50K on CCPM and any disk into an RX-33 on VMS, but I have no idea how to do the low-level formatting necessary from MS-DOS. Sadly, I "lost" my technical documentation (on purpose) during my next-to-last move. It had a complete description of the RX-50 low-level format... -Chris +------------------+ \ Chris Petersen / +-----------------------+--------------+----------------------+ / Vanderbilt University Computer Center - Systems Development \ / petersen@ctrvax.Vanderbilt.EDU .AND. petersen@VUctrvx1.Bitnet \ +-------------------------------------------------------------------+ { "You're quoting me?

Apologies to all... To (low)-level format a floppy with MS-DOS 2.11-1 (last version provided by DEC, the syntax is format d:/i<ret> (and not format d:/e). - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Claude Bersano-Hayes HAYES @ URVAX (Vanilla BITNET) University of Richmond hayes@urvax.urich.edu (Bitnet or Internet) Richmond, VA 23173 ...!psuvax1!urvax.bitnet!hayes (UUCP)
