I wanted to exercise my Dazzler and since I don't have joysticks yet, I wanted a non-interactive program. I looked around on the net and, while I found lots of references to it, I had a very hard time finding the kaleidoscope program itself. I finally found a paper tape image of it in a zip file on Dave Dunfield's web pages. There is a warning that there may be errors in these images so I disassembled the program to see where it should go in memory and whether it looked OK in general. The result is here: http://wsudbrink.dyndns.org:8080/kscope_dis.txt I don't claim to exactly understand how it works, but it looked OK so I loaded it up and it works. So that I could easily load it up under Cromemco RDOS, I relocated it to 0x3000 and made a file that you can push straight into RDOS with a terminal program that supports "transfer text to host". That file is here: http://wsudbrink.dyndns.org:8080/kscope_rdos.txt If you want to see the display that Stan Veit says stopped traffic in Manhattan, you can load it up under Richard Cini's Altair emulator with Dazzler support.
