Does anybody have the mark sense "punched" card that was used with OS/8 MSBATCH. A Basic and Fortran version was available where you used a pencil to mark up a punched card to write your programs. Scan from manual ftp://ftp.pdp8.net/misc/mark_card.jpg If so what color were they printed? Does anybody have a spare one I could get? I would like one original to show at VCF east. I am hopeing to make some and get my reader working.
