HP50g - HP-GL Interpreter

[Martin Hepperle]

The program GLPLOT takes a vector graphics file in HP-GL format and plots it on the HP50g LCD screen.

Only a subset of HP-GL is interpreted, but this is sufficient to view well known drawings e.g. from ancient AutoCAD or modern vector drawing programs.

Speed is not impressive, but may be improved by reimplementing parts in SysRPL.

This was a fun project for a few vacation days which I wanted to do for a long time.

The attached ZIP archive contains a subdirectory with individual files, which can be uploaded to the calculator using the connectivity kit for the 48G/49G,50g.
