Thanks, I know it. But I asked for someone to provide me these items in 5'25 format :-) If he/she wants to put a price for it, I'm open for comments. Actually I can't do the job of grab the IMD images in 5'25 diskettes. But, of course: - If someone knows how to install one 3'5 diskette unit in one AT&T 3B1 (being it operative) - If this unit could read 3'5 diskettes on 1'44 Mb - If it would be possible to grab the IMD images of AT&T in bitsavers in 1'44 disks ... I could try it. Kind Regards Sergio 2009/4/15 <djg at pdp8.net>
