Seeing the mention of the Shugart QD floppy drive brought to mind an Altos 586T that I used to have that used this drive, along with a Wangtek 60MB streaming tape drive. This was an 8086 based server released around 1983 that ran XENIX and used a number of Z80's to handle the I/O on both the serial ports and disk subsystem. I no longer have the machine itself as it was horribly corroded by the time I got it, though I do have a replacement Wangtek tape drive and a copy of the XENIX floppy disks for it, as well as two 3M DC300XL/P data cartridges that supposedly contain a full system backup. Short of finding another 586T, is there any way of at least checking the data integrity of these tapes? thanks and take care Jeff -- Power Computing PowerCurve, 400mhz G3, Mac OS 9.0.4 Collector of Classic Microcomputers and Video Game Systems: http://www.geocities.com/siliconvalley/lakes/6757
