rsts pip tape

Hi, I made an image of an old tape I have (I think it has a copy of the whitesmith's C compiler on it). I'm not sure how it was made, however. I think it is just done with PIP. It has a lot of tape marks separated by a variable number of records. The first record of each tape 'file' is 14 bytes. All records after that are 512 bytes. The 512 byte records are clearly the file contents. After the file contents there is a tape mark. I'm guessing the 14 bytes is radix-50 file name + info. What's the best way to make sense of this from unix? (short of running RSTS on an emulator). Is there a unix/dos program which which can interpret the data? Will PUTR be able to read and show a directory if I turn the simh format file into a byte stream? (wish putr could read simh style tape images) thanks! -brad
