OK that really seems to be 7/8" wide 7-level, even though the 1965 ECMA doc says 7-level is 1" ...?? So I just added a --whirlwind flag to ptap2dxf (and pushed it up) to make physical tape that looks like that photo. It doesn't yet do any protocol mapping or whatnot as I don't quite get the gist of the Whirlwind_Paper_Tape_Format.pdf C:\path\to>ptap2dxf --whirlwind --text="012ABC" --output=WW.DXF +--------+ | OO. | | OO. O| | OO. O | |O . O| |O . O | |O . OO| +--------+ Joiner 0000: data byte 00000000 absolute position 00000006 C:\path\to>head -5 WW.DXF 0 SECTION 2 HEADER 9 . . . (And cut that tape DXF on a CNC stencil machine. I don't have my stencil cutter set up at this moment so I just printed it on paper and measured to confirm 7/8" wide, 7 data holes) But I suppose it's all a moot point if they don't have the original Whirlwind paper tape reader device to run it through :( Steve
