Group,

Ive got a tape here from what I believe to be a VM system.  The
structure is unknown to me, although I can possibly take a stab at it.
Lots of data between tapemarks that seems to consist of a number of
records that start out something like this (translated from EBCIDC):

> 00000000  02 43 4d 53 46 30 30 30  31 31 32 30 35 31 31 32  |.CMSF00011205112|
> 00000010  34 37 30 37 36 30 31 32  32 32 31 31 30 31 31 31  |4707601222110111|

Another example:

> 00000000  02 43 4d 53 46 44 41 54  41 20 5f 4e 55 4c 4c 5f  |.CMSFDATA _NULL_|
> 00000010  3b 20 20 20 20 20 20 20  20 20 20 20 20 20 20 20  |;               |
> 00000020  20 20 20 20 20 20 20 20  20 20 20 20 20 20 20 20  |                |

The data itself appears to be a bunch of 80 character card images.

I found a mention on the old yahoo groups H390-VM discussions, but no
clarity was ever shed on the subject.

Does anyone know about this tape format?
