This is my submission to the Forndata 2022 open demo compo. The Commodore PET 8032 has: no bitmap or graphics mode no sprites no custom charsets meaning all it can do is draw characters from the standard character set. I did not find means to interact with the raster position neither, other than the vertical blanking event. This makes it fun to squeeze out some quasi graphics anyway. Learning the 6545/6845 Cathode Ray Tube Controller (CRTC) was fun and a little annoying. I guess the main point of this demo is the fullscreen balloon scroll, even though it has some esthetical flaws. It's a little tribute to the balloon sprite demo of the instruction manual of the grand child C64. There are a few things at work in that scroll: 1. soft sprites on an emulated bitmap canvas (based on cropped standard characters using CRTC register R9 "Number of rasterlines per characterline") 2. a "carefully" tweaked CRTC registry configuration mirroring the canvas below and above, creating a computationally cheap fullscreen effect. The esthetical flaws consisting of some jagged/broken balloons could possibly be tweaked by delaying the writes to the character memory. The soft sprite plotter could also be optimised a lot. The screen capture is badly done, sorry. Shout outs to Orb, their demo No Pets Allowed was amazing and a huge inspiration. /Hedgewizard #forndata #commodore #pet
