Dan,
Since you don't know much about this tape, you may want to read up on Undefined records, Deblock, SkipEof and Files in the Fcopy Reference Manual.
If I remember correctly, you could do things like:
FILE TAPE;DEV=TAPE;REC=-4096,,U,ASCII;LABEL=TMAR01
FCOPY FROM=*TAPE;TO=;CHAR;HEX;FILES=3
to dump the contents of the first 3 files on the tape.
FCOPY FROM=*TAPE;TO=;CHAR;HEX;SKIPEOF=3;FILES=4
to dump the contents of files 4, 5 and 6 on the tape.
If you see patterns in the record sizes, you can use Deblock to split them out.
Good luck.

First, since the tape AVRs we know that it is not in some compressed
mode that your drive does not
read. This is good. Second since they went to the trouble to write a
label on the tape as TMAR01,
one might guess that this stands for Tape MARch of 2001.
To see what is on the tape we can dump some of it:
file t;dev=8;label=TMAR01,ANS
fcopy from=*t;to;char;hex
Looking at the data dump we might be able to:
1. Pick out certain fields, Names, Vendors, Parts, Credit Card #s
2. Look for repeating records that would give a valid record length
3. Look for blocks of records that would give the blocking factor
