Quality, multilingual, retail and custom typefaces by Jeff Kellem

Typefaces Available and Coming Soon

The 1403 Vintage Mono Pro typeface was inspired by the IBM 1403 mainframe line printer. This all uppercase, monospaced font was recently expanded to include additional scripts beyond a nearly full complement of Latin. It now supports Cyrillic, Greek, Hebrew, and Vietnamese! This font is available for purchase. Check out the interactive specimen site designed with Kenneth Ormandy.

From a custom font engineering project converting music notation fonts to Sibelius:

As the resident font professional on this project, Jeff Kellem of Slanted Hall Type Foundry has devoted countless hours to it. …his skill is evident everywhere. Making these fonts work seamlessly in Sibelius was a special challenge, and I’m so glad that Jeff was up for the task and all of the twists and turns it took along the way.Philip Rothman

  • Resurrecting Type of the IBM 1403
    A random query, idly wondered aloud by a friend, sparked the creation of a typeface inspired by the 1960s era IBM 1403 mainframe line printer. A weekend side project to create 52 glyphs reminiscent of the A and H printer chains turned into a full-blown, uppercase, monospaced typeface supporting most languages using the Latin alphabet (including Vietnamese), Cyrillic, Greek, and Hebrew. The IBM 1403 was a workhorse, quite popular, used throughout the 1960s and 1970s on everything from bills and checks to library card/book catalogs to automobile service parts identification labels. One of the first high speed, quality, line printers, the IBM 1403 is an interesting piece of technology, using replaceable chains (including the individual metal slugs on a chain). This presentation will provide an overview of the technology and show historical samples along with the resulting typeface. TypeCon 2013, Portland, Oregon, USA, August 2013
