31-color patch kit for hp2xx-3.4.4 and executables for MS-DOS

Overview

This patch kit for hp2xx-3.4.4 is primarily designed to convert HPGL-format plot files created during the MS-DOS 3.1 era into 31-color EPS files. We have selected a set of colors that we believe look beautiful and are well-suited for printing on paper or saving as PDFs.
