Here's a quick machine code project. How about a spirograph program? The options screen is in Basic. Select your parameters for the spirograph you want to see or press R for a random series of screen savers. If you select parameter input, the program will draw your spirograph and then redraw it after a pause. Press any key to exit when it's pausing.
It draws in blue if you have a Chroma interface but will work with just a 16k ram pack in monochrome

Thanks Bukster.
Ever seen this such of program on the ZxPrinter in Basic, not on the screen !
The "PLOT" basic ROM command jump is not use... great job.

Re: Machine Code Spirograph program
Yes, I used my own quick plot routine that I wrote some years ago. I used the same routine in the version of the Arcade game 'Berzerk" named Berzxerk as it was for a ZX81.The "PLOT" basic ROM command jump is not use... great job.
