Over the next few months I'm going to be uploading to YouTube video art programs created on the Astrocade. I'll post all of the links to them in this thread; this is the first of them.
I have uploaded a ten minute video of the Viper Test Pattern by Alternative Engineering. This is a video art program for the Bally Arcade/Astrocade that was released in 1981. It requires a RAM Expansion and an extended BASIC, such as Vipersoft BASIC or Blue Ram BASIC.
I captured this video using my Framemeister setup, which is quite extensive and complicated. I plan to document it sometime in the next few months. For now, just know that this video was captured from an Astrocade with RF out. This video is one of about 60 video art programs that I've recorded over the last few weeks. The other video art programs were all written in Bally BASIC or "AstroBASIC." The extra colors of this Viper Test Pattern are neat to those who know the limitations of the original Astrocade BASIC cartridges. That's why I chose to upload this one to YouTube first.
According to The BASIC Express newsletter, "The program puts up a gorgeous ever-changing complex pattern on the screen. You would swear that 32 different colors are on screen at the same time." This is a neat program that uses some of the features of extended BASIC (such as the CIRCLE command) and the additional colors that are not available without using machine language from Bally BASIC or "AstroBASIC."
This video art program was released on a cassette tape with Viper 1 RAM Expansion. It also appeared in July/August 1981 The BASIC Express newsletter (Vol. 3, Pages 26-27) and the December 1981 Arcadian newsletter (Vol. 4, Page 19).
As I said, over the next few months I'll be uploading additional video art to YouTube. For now, enjoy one of the precious few videos that shows-off extended BASIC on the Astrocade.
