Amazing to think I\u2019ve been playing with pen plotters for over 10 years (longer if you count my first plotter, the Commodore 1520 with my VIC-20). What started out as a curiosity has continued to keep me engaged as a retro computing enthusiast and captivated as an artist. I thought I\u2019d go back in time with some of the plotters I\u2019ve used in various ways.<\/p>\n\n\n\n

My first pen plotter was the Commodore 1520 when I was a kid. There were other variants based on Alps plotter mechanisms like the Atari 1020, Radio Shack Tandy CGP-115, etc. They were a great introduction to pen plotters and I\u2019m still amazed to find the Alps mechanism stuffed into the oddest of retro tech like calculators and keyboards.<\/p>\n\n\n\n

The gears on these suffer over time and split but I designed 3D printed replacements that have been working well for me.<\/p>\n\n\n\n
