This actually wasn't all that long ago.  Certainly recent enough for 
drum-scanners to be somewhat more common than they used to be.

Surprisingly, there are still companies out there running Bull 
DPS9000-class mainframes.  Not many, but one here and there.  These 
people had been doing their data transfers in and out of their DPS8 box 
by tape, but their last tape drive had just died, and so they decided to 
rid themselves of the machine.  However, they had some data they hadn't 
backed up, and they wanted it in an IBM format.

I just drum-scanned into TIFF and used OCR software on the PS/2 to do 
the heavy lifting.  I used the PS/2 because 3270/A cards are a dime a 
dozen and I happen to have a rather large pile of PS/2 equipment lying 

Peace...  Sridhar
