Now, the real question: A friend of mine has a magtape written on a HARRIS/4 (I think that's the model number - definitely the make, anyway), which contains vital data. The tape is unlabelled. However, the biggest problem is that the record and block size on the tape is - are you ready - 98,640 bytes. As most of you probably know, both VAXes and IBMs can only handle a maximum blocksize of 64K (65,534). Does anybody know of any way around this? Is a HARRIS the only machine that can read a record this big? Can VMS be "fooled" somehow, either by changing a value in some location, or by fudging tape operations (the latter is not a method of choice since they only have one copy)? VMS-oriented responses are welcome (although I am sure most will be "you're out of luck"), but if anyone has ever come across a similar situation, I would also appreciate hearing from you (as would my friend, I am sure). Thanks in advance for answers to this very-humble request.

Any VAX/VMS hints will be posted.
