Keypunch029 — for all your punched card font needs …

A fairly accurate rendition of the 5×7 dot matrix font printed at the
top of punched cards by the IBM Type 29 Card Punch (1965).

The 029 (as it is sometimes known) generated a bitmap font from an engraved metal plate pressing on a matrix of pins. A picture of this plate from a field engineering manual was used to re-create the pin matrices, and thus an outline font.

Historical Accuracy

The 029 could have many different code plates, but the one used here contained the characters:

<=>¬|_-,;:!?/.'"()@¢$*&#%+0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ

The character glyphs have been sized such that if printed at 12 points, the 029’s character pitch of 0.087″ is accurately reproduced. No attempt to research the pin matrix pitch or pin diameter has been made: the spacing was eyeballed from a couple of punched cards in my collection.

The earlier IBM Type 26 Card Punch (“026”) included a glyph for a square lozenge (Unicode U+2311, ⌑). The 029 code plate did not include this character, but I added it here for completeness.

The character set was extended to include:

  • all of ASCII, with lower case characters repeating the upper case glyphs;
  • sterling currency symbol; and
  • euro currency symbol.

While there may have been official IBM renditions of some of these additional glyphs (with the exception of euro) no attempt has been made to research the original shapes. This font set is intended to help with the visually accurate reproduction of 1960s-era punched cards, mostly coinciding with my interest in the FORTRAN programming language. No attempt has been made to use historical BCD/EBCDIC encodings in these fonts. We have Unicode now.

The 029 card punch could not produce any bold or italic font variants, but FontForge can, so I did.

Things I learned in making these fonts

  1. The 029 card punch printer could be damaged if you tried to print binary cards, as there was no way to disengage the code plate from the punch mechanism.
  2. FontForge really hates to have paths in a glyph just touching. Either keep them more than one unit apart, or overlap them and merge the overlapping paths.
  3. EBCDIC is weird.

Library Hand – Disjoint


LibHandDis — Based on scans of “Library Hand – Disjoint”, described in Dana’s A Library Primer, with some modifications.

Major changes from scan:

  • As the scan only covered A-Z, a-z, 0-9 and ‘&’, I had to make the rest up.
  • Many of the descenders had to be shortened to fit with modern typography conventions.
  • Kerning is much tighter than Dana’s guidelines suggest.

(idea for this came via MetaFilter, This question of library handwriting is an exceedingly practical one)
