I have a VAXstation 2000, but it only has a 71MB disk. TK50's will hold 95MB. TK70's (found on the MicroVAX 3xxx's) will hold 296MB. Here's some more *exciting* information about the TK50 (from Appendix A of the "TK50 Tape Drive Subsystem User's Guide" #EK-OTK50-UG-004): Mode of operation: Streaming Read/write method: Serpentine Recording method: MFM Recording medium: 1/2 inch wide, 600-foot long mag tape Start speed: 130 msec min, 300 msec max Stop speed: 90 msec min, 130 msec max Start distance: 5 inch min, 12 inch max Stop distance: 3.5 inch min, 5 inch max Recording density: 6667 bits per inch Number of tracks: 22 Data rate: 360 Kbits/sec (45 Kbytes/sec) Tape Speed: 75 inches per second Read Time: 35 minutes for a full tape Storage Cap (unformatted): 131 Mb Regards- +---------------------------------------------------------------------+ | Mark H.
