![]() Thanks to the epic efforts of Jim Brain and others, this ROM is now archived on Project 64 Reloaded. I never owned one, but it seems it was more of a curiosity than a useful product.įrom a nerdy point of view, however, this device was rather clever in that it packed a whole plotter command language, including a usable font, into 2048 bytes of ROM. ![]() – This file was derived from Cbm1520-2.jpg:, Public Domain, It looked like this: Commodore 1520 printer plotter — by Oguenther (Dr.Guenther). The Commodore 1520 was a tiny pen plotter sold for the Commodore 64 home computer. I had the great pleasure of meeting Josh at XOXO 2016, too. Update, September 2016: this font was officially squee‘d over by Josh “cortex†Millard on the Metafilter Podcast #120: Hard Out There For A Nerd. Please note that the font will cause your device to follow the tool path of each letter twice.ĭownload: FifteenTwenty-master.zip FifteenTwenty-UltraLight.zip (or more options …) Published 0įor the impatient: download FifteenTwenty-master.zip FifteenTwenty-Regular-OTF.zip (or more options …) This font is almost invisible on screen or on a regular printer, so I don’t recommend installing it unless you have specific CNC/plotting needs. Here’s the hairline font plotted with a 0.7 mm pen to illustrate what I mean: If you have a device with a defined tool width, it’s better to let the tool make the width of the mark/cut. Single-line (or stroke) fonts used to be possible in PostScript — the version of Courier shipped with early Apple LaserWriter printers was composed of strokes, rather than filled paths — but have fallen out of favour. This is a slight misuse of the OpenType format, but if you’re plotting/CNCing/laser cutting, the filled paths of standard fonts don’t work so well. Jones’s punched card index is all about punched cards.įollowing on from FifteenTwenty, I made a hairline/single stroke version of the font especially for CNC use. The site’s owner is part of the IBM 1401 Demo Lab and Restoration Project. IBM029-Field-Eng-Maint-Man-r.pdf – see page 59 for the code plate image.Norbert Landsteiner’s amazing Punched Card Typography Explained page describes how the code plate system worked, and has JavaScript animations showing how characters were decoded (entirely mechanically) from the plate.Either keep them more than one unit apart, or overlap them and merge the overlapping paths. ![]()
