I think you are mixing up the 60 MB tapes with the older 23 MB tapes ( from the 3B2/400 or XM ). To my knowledge the 23 MB tapes were the only cartridge tapes that needed to be formatted ahead of time. I KNOW that I have written a 60 MB tape on a 3B2/600 and read it successfully on a 6386. In fact, it was the first thing I tried once I got my hands on a tape drive for the 6386. ( this was using cpio ) -- Hans Jespersen hjespersen@trillium.waterloo.edu uunet!watmath!trillium!hjespersen

Nice to hear that newer 3B's have compatible drives. (This doesn't help us though since we have to live with an old 3B.)

The only problem then is that you need enough empty disk space to copy in 125M of data to fill the 386 tapes. Les Mikesell

Unless you have patched the tape controller on your 6386 (Fix #81) with new ROMs, you will not be able to read 6386 written tapes on your 3B2/{5,6,7,10}00, Sun, etc. Bud Greasley SoftQuad Inc. bud@sq.com
