Still have my VIC 20. Used it QUITE recently in fact to build some crosshatches and color bars just for fun. Used it recently to just create a big white square on a black background when I was playing with the Sony S8-301's horizontal instability.
It's little curvy cassette drive DIED a few years ago....and I had to just resort to "recording" my funny little test patterns with my Archos AV700 for use later on my little internal transmitter. I know I coulda used Windows Paint to do this....but using the VIC 20 was fun after so many years
