Here's a small demo I did during the Vintage Computer Festival Europe in Munich (download).
The main screen was done on the VIC-20 shown there, with Lightpen on a TV set (i.e. with RF-Modulator), much to the delight of the presenter.
In the evening between those two days I complemented the main screen with a small raster demo.
It's the 101% release, which fixes a small error in the original release. You'll need at least a +8K RAM expansion to run the demo.
I could also secure an original VIC-1111 and VIC-1211A, both boxed and with instruction leaflet.
Cheers,
Michael
