xmc -> the card deck is small enough that I'm having the owner scan it up as a PDF and I'm going to tediously transcribe it by hand, from what I've been able to Google, the common practice was to use the last 5-10 columns to preserve card order in a deck ... and the data has some checksum totals that'll probably work out. |

(the BSD game 'ppt' item has a to/from translator for papertape ASCII but I think manually slurping the data out with patience and vim will work ;) |

xmc -> Each card holds 80col, the card data is roughly like http://i.imgur.com/gTTxv0Y.png (almost all bytes will be ASCII [EBCDIC?] '0'-'9') |

xmc -> I'm each column will represent an EBCDIC or ASCII 0-thru-9 or SPACE , so hopefully the transcription burden won't be too crazy. :) |
