Brad,
If it is in DOS-11 format, I can read it on my vax, if it is 1600 or
6250 BPI. The vax will read ansi tapes in native mode, and with
EXCHANGE, it iwill read DOS-11 tapes. Also, I've found out, I can at
least read it in using BIGTPC and sometimes
get a directory once it is on disk.

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!
